High risk pregnancy, ultrasound at 5w2d.

fancirb

Gs was visible and looked like a tiny speck(lol couldn't think of better language atm), yolk sac was not visible.  I'm not sure if "speck" was ys because it didn't look to be circular or hollow. I wished I could upload a picture dr. gave me to give a visual. 
I was diagnosed with Mthfr less than a year ago. I am currently on my 8th pregnancy with 2 live births(first 2 pregnancies), 4 miscarriages, and 1 ectopic. Dr. prescribed daily lovenox shots, bb aspirin, and tripled my intake of progesterone. Since pre pregnancy I've been on folate supplements. Once I had a bfp I was prescribed progesterone capsules. Also, my hcg levels were 27,000.
I'll see my doctor again in 4 days, I'll be 6weeks. I'm hoping everything is going to be ok, I dont think my husband and I can go through loosing another baby. We've been together since high school and have 2 beautiful daughters who are 7 and 8, I haven't told my daughters any news yet because one still has a very hard time as well. I'm trying not to stress, but it's the only thing on my mind since I got my bfp.
