I have been having unprotected sex with my partner. I was a few days late on my period. Then, I started experiencing minor cramping. I now have a little bit of beige colored vaginal discharge. About the size of a quarter-- a whole days worth. I took a home pregnancy test right before I started experiencing the cramping and spotting. It was negative. So the time frame is: 1/23/2011-- took pregnancy test that was negative. 1/24/2011 started mild cramping and beige colored discharge. It is now 1/27 and I am still experiencing the strange discharge and little bit of cramping. What could be going on here?
