Hi. I Am Neha. 32 Years Old. I Have A

hi. i am neha. 32 years old. i have a 8 year boy with normal delivery. since last two years i am planning to extend my family but i had two missed abortions back to back. after 1st missed abortion, i was diagnosed with ANA positive and SLE BUT NO LUPUS. . so in next pregnancy my Dr put me on baby aspirin and heparin. but unfortunately d baby heart beat stooped in 10th week. now am taking hcqs 400. My query is that is there still a risk of miscarriage in my case while taking hcqs ,heparin and aspirin. can ivf with donor egg subside the risk of miscarriage?
what are the chances of carrying a baby to full term with positive result?
early reply will be appreciated.
thanks and regards.
