PLEASE HELP!

Halie
My last period was june 23-26th. The 26th i had sex, more in the morning so technically the 27th. Then the 28th in the morning took morning after pill. (Not on birth control) then i had sex july 2nd, the condom broke, took morning after pill that next morning. I was suppose to get my period june 21st, but i still have not got it. I started birth control yesterday (the pill). My breasts feel weird, not sore but weird & i have like period cramps once in awhile. And im gasy. Please help am I pregnant? Only 17.
