Query regarding ibs after pregnancy.

Hello doc.. since Dec to Feb start I was suffering from gas pains in stomach.. and motions problem also(sometimes)... I showed to many doctors they were treating me as IBS.. and gave many medicines.. which didn't work at all.. then in Feb start I showed to another lady doc.. who changed my thyroid dosage.. and I was feeling fine.. only during ovulation I had stomach pain then.. But then I concieved and this problem had vanished all together.. In pregnancy I didn't face any such problem.. My question is once I deliver the baby.. will I be normal like I am now during pregnancy or will I have the same issue which I was having before concieving.. I got this doubt because yesterday I had chicken and I felt bit of gas pain in night which made me scare to remember all the past sufferings.. Please reply...
