Hi. I'm 19 years old, i've always been irregular since the 1st time I had my period. Most of the times, my period are every other month. But starting november 2014 until 2015 my periods are coming every month. My last period was last March 25, 2015. I am delayed for months now. Period didn't came up until today, May 25, 2015. I don't know what's going on. Pregnancy test says it's negative. My boyfriend and I had sex last April 8, 20 and May 8. Could it be possible that I'm pregnant? I'm not experiencing any pregnancy symptoms but last last week, around May 11 to 15, I had several clear watery discharge. I thought I'm gonna have my period but when I go to the bathroom, it's just a discharge. Please help me. Thanks.
