Question: Hi,

I am currently 7 to 7.5 weeks' pregnant (uncertain of first day of LMP). I have a history of recurrent pregnancy loss (3 miscarriages since 2010, one live birth in 2013, most recent miscarriage in September 2017). I am on progesterone suppositories 3 x per day, Heparin injections 2x per day (tested positive for PAI-1 4g/5g), baby aspirin, and 5 mg folate. I had HELLP Syndrome and preeclampsia with my daughter. I also have a history of hypothyroidism and am on 85 mcg of Synthroid.

I am worried about another miscarriage and have been told by my reproductive endocrinologist that I should be 'guarded'with this pregnancy. My scans (I have had 3 so far) show growth. The most recent scan (4/17/18) showed good growth with a yolk sac present, which had grown appropriately since the week before. The ultrasound tech and nurse practitioner both felt that a heartbeat could not be seen because the yolk sac was so close to the wall of my uterus. I measured 5w6d, although I thought I should have been close to 7 weeks by then. I felt very hopeful after seeing this most recent scan.

What has me very worried are my Beta HCG levels. The measurements were as follows:

3/27/18: 246
4/3/18: 1447
4/10/18: 3048
4/17/18: 3278

I still very much feel pregnant (sore breasts, nausea, tired, aversion to certain smells and foods).

Are the very slow rising Beta HCG levels something I should be overly concerned about, or is it enough that the scans show growth? Do women with HCG levels like mine ever go on to have live births, or should I prepare for the inevitable miscarriage?

Thank you so much for your time!
