In 2014 I had a medical abortion where I was given a shot with a substance that stops the growth of the fetus/child. Then they give you pills to open the cervix so the fetus will just fall out. I googled the name of the chemical used in that shot and there’s possibility of infertility. I have three boys-13,11&6. I’ve been trying since September 2018 til now to get pregnant. Should I be worried?
