some one please advise, i had intercourse sometime back in september (it was my first time in over a year) i got some bleeding in october but only for three days and not heavy (wore panty liners the whole time), november comes and completely missed my period took a hpt and it was neg. im having clear discharge, lower abdomen cramps (as if im going to start my period) bloating and my breast are not to sore but my nipples are. my lower abdomen feels a lot firmer than before too. I'm very concern due to the fact that a couple years back I had a tubal pregnancy and definitely don't want it to happen again. please help with some advise to what further step i can take or how long i should wait before seeing a MD. thanx in advance!
