I still haven't gotten my period and it's day 37. After getting off the pill I had a 30 day cycle then a 33 day cycle, now it's day 37 and no period. My breast are sore and that's it. They were sore last month from a week until I started until after I started. I'm assuming it's coming because of the sore breast. I don't have other signs of my period. I wish something would happen. The hpt said negative when I took it yesterday. We were trying in december, but decided to wait until march so we used condoms all but three times in january. This is so frustrating. If no period by monday, i'm going to the gyno. It can be so many things. I wish i'd just know.
