Not sure what to do or expect. My LMP I fear was unreliable. It came early with clots & started & stopped, lasted way longer than normal & even started at a 23 day cycle - my average is 27 days. I found out I was pregnant extremely early because I have Fibromyalgia which made my pregnancy hormone symptoms intensified. I know exactly when I had intercourse Feb 14th & Feb 16th. Identified pregnancy March 3rd.. I have another ultrasound 2moro. But so far they keep saying ectopic cuz the don't see where it is & since I'm slow rise hcg. My diet is not good, was worse before I found out. Rarely eat. Among medications & a handful of health conditions - I have looked online, but there isn't much that includes all my factors. And until I get something to show on ultrasound they can't put me on medical coverage so for now I have a low income clinic & I feel as though maybe they are out of their limitations for accuracy on my situation. I'm very uncertain what to think. I feel as pregnant as I did with my 1sy child at 6 months along, but since I've developed Fibro I know my symptoms are unreliable. Any advice? Anyone have 700 hcg at 6 wks & still have a normal pregnancy & child? Or anyone have hcgs only double every 90ish hours? I'm 33,have been waiting 6yrs for a pregnancy w/my new partner. Any information anyone can provide? I'm a bit concerned. Thank you.
