Still confused 🤷‍♀️

Anon

So I posted last night while in the ER but have since deleted that post. Anyways, the only time I had sex that would have gotten me pregnant is july 25th, I got my super faint positive august 7th and later confirmed with 6 more tests including digitalis. Based on my last period I would be 5 weeks 2 days. My midwife said my hcg level of 762 would be normal for doubling every 48 hours if I got a negative the day before I got a positive meaning me levels were super low so she isnt worried, but the er couldnt see a sac or anything but uterine thickness. Can I just be earlier than I thought? That's what my my midwife thinks but again I only had sex the one day. I'm supposed to go in again in a few days but I'm confused now. 🤷‍♀️

No cramping or bleeding.
