Hi. That's always really scary. But our cervix when pregnant is closed and easily irritated. It's very vascular so those blood vessels can bleed. This could be the situation. I always had spotting prior. The hormones of pregnancy also can cause dryness and that makes it even more easy for blood vessels to become irritated and cause bleeding. This is not uncommon. You've presumably had ultrasounds at this point, correct? Do you have placenta previa? That's when the placenta covers part of the cervix. I had this when pregnant and many women do but the placenta normally lifts as the pregnancy goes on. You'd have been told if you have this situation.
I would not worry (although we always do). I'd tell your doctor at your next baby visit. Are you going twice a month yet? Or go ahead and call the office. They normally have a nurse or the doctor themselves are happy to chat about these things and tell you if you need to come in or what to look for if there is an issue. IF you still have active bleeding or spotting or cramping, obviously call your doctor immediately and seek medical attention. In my third trimester, even during the doctor exam to check my cervix, I had cramping and spotting. My cervix was extremely sensitive. No one told me that and I was really worried the first time it happened. So, it is probably fine. Check in with your doctor verbally with a phone call. Go to the doctor right away or even to triage (wherever you are delivering at) if things become a situation of ongoing heavy bleeding, cramps, etc. Let me know how it all works out, okay?
