According to the doctor I've had sex with my husband on Friday night.. that's​the reason why I lost my baby... And another one is folic acid+ iron tablets are not recommended for first trimester of pregnancy.. I took 3 tablets for three days and had sex.. is this a correct reason of my miscarriage.. because everywhere in internet there is a statement that "it's really good to have sex during the pregnancy..." so what you ppl think of it.. please response
