I just had a baby 2 months ago started birth control pills and now im on my second period for this month, how do i get it back to normal?

Takes awhile: Sometimes it takes awhile after having a baby to get a normal cycle back. If you're breastfeeding, that can be even more so. Give it some time, your body is still adjusting. Regular exercise, and a good diet, in addition to getting some sleep (i know, hard with a new baby), will help as well.

Pills will regulate : I assume you're taking a combined oral contraceptive pill. If so this will eventually regulate the cycles. Just stay patient and usually within three months cycles go back to normal. If you are taking a Progesterone only birth-control pill and cycles might not be regulated.
