I need advice, and this might be TMI but my husband and I were having sex this afternoon and I am 10 weeks pregnant. During Sex, I noticed some blood. Not too much just a little bit, and I made him stop. It wasn’t painful and I haven’t had any other symptoms. Its been about 4 hours now and I just got up from a nap to use the restroom and saw a little more blood. It is red like its fresh, not dark like it was old. What should I do? I had an Ultrasound on the 28th of March and everything was great, should I be worried? Is this normal?
