Hi,
Let me start by saying that once your wife has conceived , her chance to conceive again is very high.
Ecospirin is a medicine which makes blood less thicker/ less chances of clotting. When baby sits in uterus blood has to be thin to reach it. but in some conditions this thinning doesn't occur & blood flow to baby stops gradually & baby dies. But this medicine is required only when she gets pregnant, I mean when her urine tests positive. The other indication for taking it is if she has DVT ( Deep
Venous Thrombosis) or clotting tendency even before
pregnancy, but then she will need it for life long , why 3 yrs!!
She should have an APLA testing done ( Anti
Phospholipid Antibody Syndrome) before next pregnancy. If abnormal start Ecospirin once urine positive & she will need
Heparin injections daily once heart beat is seen on scan.
Kindly see if the following checklist of investigations is done
Husband-
Semen analysis at least 2- done 4 weeks apart preferably in an
infertility center ( examination done by andrologist), Blood sugars
Wife - Blood Sugars, Thyroid profile
Ultrasound scans to evaluate Uterus , Ovaries & adnexa
Confirm tubal patency- most important- Tube is the connection
between uterus & ovaries( the bridge where sperm meets the egg &
forms a baby) this is size of hair follicle & cannot be seen on scans.
So check with HSG( Xray with dye), or SSG ( Scan with dye) or Laparoscopy
If all this done & found normal , nothing can stop a pregnancy with God's will
Hope I have clarified your query
All the best
