Hi .....i had 3 abortions 3 years back due to some medical problems, now after 3 years i was able to get pregnant again, but on 39th day when i went to doctor for pregnancy test, she confirmed that test was negative and gave me medicines to get my periods, after taking the medicines, i didn't get my periods for 10 days. when i went to the doctor again, she confirmed that i was pregnant. but after 4 weeks,i got aborted automatically. is the abortion due the medicines i used before???
