Helpp!

So my SO and I we're having sex last Friday evening. When we were finished I noticed I was bleeding, nothing super heavy, more like a light period. We went to the ER and got checked out. Babys heartbeat was there, but was extremely high compared to my 8 weeks scan( 143bpm) I'm now 10 weeks and the heartbeat was 179 when we were checked out. I was put on pelvic rest until I can get checked by my OB (tomorrow morning) any other moms experience this and baby turned out okay?
