Welcome to HCM.
You did unprotected sex with taking ecstasy
drug. Now your wife has missed period.
So do a home pregnancy
test with urine or blood test
for hcg to confirm pregnancy.
Check the result and consult with your doctor.
If pregnancy test is positive,then do a USG scan around 6-8wks for evaluation of fetal profile.If all fetal parameters are well enough,then continue pregnancy.
Need periodical check up to your doctor along with take folic acid
and nutrient supplements.Avoid heavy work and long journey.
Be well and happy journey for pregnancy.
