Spotting during pregnancy is most commonly pink, brown, or light red. The color tells you something useful: it reflects how recently the bleeding occurred and, in some cases, what’s causing it. First-trimester spotting is common, occurring in 15 to 25 out of every 100 pregnancies, and the shade you see on your underwear or when you wipe can help you understand what’s happening in your body.
What Each Color Means
Spotting refers to just a few drops of blood, not enough to fill a pad or tampon. The color you notice generally falls into one of three categories, and each points to something slightly different.
Pink spotting is blood mixed with normal vaginal discharge, which dilutes the color. It’s common in very early pregnancy around the time of implantation, and again in the final weeks as the cervix begins to soften and prepare for labor. Pink spotting can also appear after sex or a pelvic exam, since the blood vessels in your cervix carry more blood during pregnancy and are easier to irritate.
Brown or dark brown spotting is older blood that has taken some time to travel from the uterus or cervix to the outside of your body. Because it’s been exposed to oxygen longer, it darkens. Brown spotting is one of the earliest signs of pregnancy for some people, and on its own it’s generally not a cause for concern. That said, dark brown discharge that persists or increases is worth mentioning to your provider.
Bright red spotting means the blood is fresh. A few drops of bright red blood can be perfectly normal after cervical contact (sex, an ultrasound probe, or a pelvic exam). However, bright red bleeding that increases in volume, soaks a pad, or comes with clots is no longer spotting. It’s active bleeding, and the distinction matters.
Implantation Bleeding
One of the most common reasons people search for spotting color is because they’ve noticed light bleeding before or right around a missed period. This is often implantation bleeding, which happens when a fertilized egg attaches to the uterine lining, typically 10 to 14 days after ovulation. Most people haven’t taken a pregnancy test yet when it occurs.
Implantation bleeding is usually pink or brown, never heavy, and lasts anywhere from a few hours to about two days. It stops on its own. The key differences from a period: it’s much lighter (a few drops rather than a flow), shorter, and doesn’t intensify over time. If you’re unsure whether what you’re seeing is a light period or implantation bleeding, the timing and pattern over the next day or two will usually make it clear.
Cervical Sensitivity and Spotting After Sex
During pregnancy, blood flow to the cervix increases significantly. This makes the small blood vessels on its surface more fragile and more likely to bleed with even mild contact. You might notice pink or light red spotting after intercourse, a transvaginal ultrasound, or a routine pelvic exam. This type of spotting is typically brief, resolving within a few hours, and doesn’t indicate a problem with the pregnancy itself.
Subchorionic Hematoma
A subchorionic hematoma is a collection of blood between the uterine wall and the pregnancy sac. It’s one of the more common causes of first-trimester bleeding that shows up on ultrasound. The spotting it produces can range from light to heavy and may include small clots. Color varies depending on how quickly the blood exits: fresh bleeding tends to be red, while older collected blood comes out brown. Pelvic cramping alongside the spotting is possible but not typical. Most subchorionic hematomas resolve on their own as the pregnancy progresses.
Bloody Show in Late Pregnancy
If you’re in your final weeks, the spotting you see may look quite different from early pregnancy spotting. The “bloody show” is a discharge of blood-tinged mucus that happens as the cervix begins to dilate. It can be red, brown, or pink, and it has a distinctive jelly-like, stringy texture because it contains all or part of the mucus plug that has sealed the cervix throughout pregnancy.
Some people see mostly mucus with just streaks of blood, while others notice a more uniformly pink or brown discharge. The total amount is small, no more than a tablespoon or two. Bloody show is a normal sign that labor is approaching, though it can appear days or even a couple of weeks before contractions begin.
Spotting vs. Bleeding: How to Tell the Difference
The language your provider uses has specific meaning. Spotting means a few drops of blood, not enough to cover a panty liner. Mild bleeding means you’re soaking less than one pad in more than three hours. Moderate bleeding means soaking more than one pad in three hours. Severe bleeding, soaking one or two pads every hour or two, is a medical emergency for anyone, pregnant or not.
Tracking both the color and the volume helps you communicate clearly if you need to call your provider. A note on your phone with the time, color, amount, and any accompanying symptoms (cramping, dizziness, shoulder pain) gives them what they need to advise you quickly.
Colors That Signal a Problem
Green or yellow discharge is not normal spotting. It suggests an infection, most commonly a sexually transmitted infection like chlamydia or trichomoniasis, and needs treatment regardless of pregnancy status.
Any color of vaginal bleeding paired with severe pelvic or abdominal pain, extreme lightheadedness, fainting, or shoulder pain can signal an ectopic pregnancy, where the fertilized egg implants outside the uterus. Ectopic pregnancies often produce light vaginal bleeding as one of their first warning signs, but the bleeding alone may not look dramatically different from normal spotting. The accompanying symptoms are what set it apart. If a fallopian tube ruptures, the signs escalate quickly to shock and fainting, which requires emergency care.
Bright red bleeding that increases in volume, especially with clots and cramping, can indicate a miscarriage. Not all heavy bleeding means a pregnancy loss, but it always warrants prompt evaluation.
