I finished my period last week Thursday & had sex the Friday ( I've been on the pill - Jasmin for a year now & the last time I took the pill was that Friday morning) which was unprotected. Friday, Saturday & Sunday I was fine but Monday morning I started bleeding again. at first I thought it was my period but I had finished it last week & I had a very heavy flow, clots were coming out & it was so much that when I go to the toilet some of the blood still remains after I have flushed. I have also been having dull/irritating cramps & dull back aches at the bottom of my back which makes it uncomfortable to sit for long & sleep. today the same thing is happening, heavy flow with cramps. I am going to see my doc but I would like to know if I could have gotten pregnant & if it's possible that I am having a miscarriage? in such a short amount of time? is that possible?
