I just started bleeding (quite a bit of bright red blood, and a few clots, one being dolar coin sized). Tech just did an ultrasound and said baby looked okay with a heartbeat of 160 and was measuring 7w4d. Any insight as to what this may be while I wait for my doc to get back to me on Monday?

Update (6/9/19):

Thank you for all of the hope ladies, it was a terrifying experience for my husband and I. We don't get to see the doctor until tomorrow, but we opted to do an elective scan today to make sure baby was still there, and got to see little one for more than just a few seconds. Baby is measuring 8weeks (sac is 7w4d), and heartbeat went up to 170bpm. Thank you!
