Update: 2 week follow up ultrasound is now

measuring 6 weeks. Exactly two weeks ago I was

measuring 5 weeks 3 days. According to my LMP I

should be 7 weeks 5 days today. I am even more

concerned than before considering the fact that

baby appears to only have grown 4 days in size in

two weeks. Tech seen a flicker but couldn't

confirm heartbeat. At this point I am preparing

myself to hear bad news. I also want to mention that I had to take azithromycin at 4 weeks & I can’t help but to think that may have caused a miscarriage.
