I am sorry to know about your loss.
When you got aborted- was that your first pregnancy? You must understand to see a OB-GY doctor who has lots of credits on his/ her name of treating patients properly.
A person when gets aborted has to be compulsorily evaluated for the reasons of abortion. Patient should not be given this type of 'infertility' kind of treatment right away which you underwent. It is always normal to have midcycle spotting and there is nothing very abnormal in it.
Continue your Folvit, and not the iron unless warranted and go to a very experienced OB doctor. She/he should first evaluate for the reason of spontaneous abortion
and then treat you appropriately for any reasons revealed during the evaluation and then should advise you further how to plan the pregnancy. You do not need these kinds of hormonal
medications by indirectly labelling you 'infertility patient'. Please understand and take care.
