Bleeding after sex

ju

Last Thursday I had some bleeding after sex. We were supposed to leave for vacation that night so we went to the ED to make sure everything was ok. I was only supposed to be 8 weeks and 2 days. I measured at 8weeks 5days. US looked good. Baby was good. Heartbeat was 174. HCG was almost 127,000. No bleeding since. Still nauseous and boobs still sore. I’m still worried! Anyone else have this? I will be 9 weeks tomorrow and have my first OB appt next week.
