Im 27 year old and mother of 2. I had unprotected sex in june 10th and ever since middle of july I had some pregnancy symptoms. At first nausia but not as bad as I did with my other kids, tired a lot, moody, tired, body ache, my breast hurt (nipples) when touched, some cramping..My last period was end of june, then I was supposed to get period at the end of july..It was late( I have history of iregular periods) and I took preg test that was negative and just 3 days ago I had some dark brown discharge with a bit of dark blood but very dark. I had it for 2 days and its gone now. Is it possible that Im pregnant?
