Spotting at 15 weeks

Just went to the bathroom and noticed some pink spotting when I wiped. It wasn’t a lot, but I have a history of miscarriage, so all signs of blood are anxiety inducing for me. I haven’t had any exams or sex recently, but I did throw up sort of violently 3 times this morning. Hoping it’s just an irritated cervix from that strain.

I called the doctor, but am waiting on a call back. Could really use some reassurance in the mean time.
