I am 24 years old i have always been on a low hormone birth control last year I had two periods, one on April 1st and the other on April 15th, it was full on period that lasted about a week to 2 weeks each. I got pregant about may and had a baby on january 17th. My 5th week visit i was put on loestrin 24 and I didn't get my period until March 7th because I havent had a period in along time I stopped taking the birth control last month. today May 30th is when i finally got my period again.

I have taken pregnancy tests all negative, and since i was on birth control my husband has been using condoms. What is going on with my periods??
