A bit confused...

Christina • Sun, May 31

So since March my AF has been weird.. I started my AF in February on the 14.. then March 19.. then April 24 now in may and I was supposed to start yesterday the 30th and nothing.. it seems like now I have a 35 day cycle.. my boobs are so sore.. I took at pregnancy test yesterday and BFN.. could I be pregnant or just my body being all wacky.. :)
