Hi, for last two months iv e had very unusual bleeding, last month for instance my period was very light and lasted a couple of days. and a week after that I had brown streaky discharge, now today my period is due I again have had brown/pinkish discharge with after effects of a clear discharge with streaks of blood through it. I of course am quite concerned as my periods are usually heavy an d last up to FIVE days the least! .. other symptoms I ve been experiencing also have been sore boobs that have enlarged with prominent vain s and dark nipples. However I have taken numerous pregnancy test and have come back negative each time, A couple of times iv e even taken one in the morning as they say you HCG level is higher, so this has left me with great confusion and worry! could i actually be pregnant ?
