Prayers that everything is ok. I've personally never had betas done at that point in pregnancy so I've nothing to compare yours too but as others have said, all that matters is that they're doubling as they should. I bled in early pregnancy when I was pregnant with my DS. It was more than spotting because I had to use a panty liner. You may also be bleeding from the transvaginal you had done. With my early miscarriages I never had any bleeding until I would have been 9 weeks. I found out about them by having any ultrasound that showed no heartbeat but I was always between 7-8 weeks when I found out. You're unlikely to see a heartbeat on ultrasound until your hcg levels are at least 10,000 so you more than likely wouldn't see one anyway this early. I'll keep my fingers crossed for you! Please keep us updated!
