Just wanted to share with you all something that happened to me today in case you find yourself in a similar situation. I started bleeding fairly heavily in the midst of making love with my husband, and I noticed a lot of tisse in the blood. It scared me so much! I called the midwife, and she told me that I only really needed to be concerned about bleeding if I were going through multiple pads in an hour. Turned out that the bleeding was really just a short-lived, 2-hour episode of light spotting after the initial bleeding. Apparently the cervix is very susceptible to bleeding during sex, especially between in the 7-9 week period. I'm relieved to know that it seems like everything is okay! So, if you start bleeding in the midst of sex, too, don't worry unless it's very, very heavy for a prolonged period of time.
Happy, healthy pregnancy, all.
