OK I had unprotected sex 2 days before and the day of ovulation. A few days after that I began cramping worse than period cramps. It feels like a lot of pressure in my uterus. I can only explain it like it feels like I just had a c section. I can't lay on my belly. And is very uncomfortable to bend down or to lift things like a laundry basket. I only cramp during the first 2 days of my period. I am not supposed to start until the 18th at the latest, Im always on time. My breasts have darker veins than usual. I don't remember having this pressure feeling with my son 2 years ago.I do not have any symptoms of a UTI or bladder infection and was already tested for that and it was NEG. I don't know what to think because I thought it was a little soon to feel any symptoms.Has this happened to anyone else and what were your results? I need to put my mind at ease until the 18th. I also have an internal ultrasound set up for this Tuesday but if I am pregnant I will only be 3 weeks and 2 days, so I'm not sure if it would show up or not,I'm not sure if they would even be able to see anything. I really want it to be positive. Im not Trying to conceive but it sure would be awesome I just don't want to get my hopes up. So any feed back would be much appreciated! Thanks in advance!
