What is this ?!

So this morning around 4 am I woke up with really bad stomach pain and breast pain.(  Worst ive ever had if its cramps)
​Well in the beggining of the month boyfriends condom broke and again im not on any type of pills , shots , etc.  so what could this be?  Ive been going to the bathroom a lot , I have food cravings which i wouldnt normally eat.
