I have irregular cycles but I have never skipped a whole month. The last time I had my period was in june. It is now august 15th and still nothing. I am experiencing a lot of watery white discharge, and I've recently had on and off lower back pain along with on and off mild cramps. I am sexually active and the only form of birth control my boyfriend and I use are condoms. I have taken 4 hpts, 2 being first response (the pink ones) and the other two were first response as well but they were the extra sensitive ones and they all came back negative. I don't know what is going on with my period! Please help!
