I'm 33 and have no idea whats going on...I had sex on 11/13 (a condom was used) and through my online reasearch found out I was ovulating on that day as well. 2 weeks later (11/27) I got my period. This period was different. The flow was different than my normal periods also my normal periods last 6 days with the 6th day being very light or spotting but this period lasted 7 days. Well through out my period and after it ended I kept having pregnancy like symptoms. I would get slightly nausea and sometimes in the middle of eating or I would smell my food I would feel sick and have to stop eating. My breast hurt from time to time, my back and sides would hurt (sometimes my sides felt like they were pulling to the front) and my hips would hurt. I kept feeling like I was getting my period but it had already ended. I have blue veins across the top of my breast as well as down my sides of my belly. My nipples looked bigger. At work in the middle of the day I'm falling asleep at my desk. I took a HPT and it said neg. Well during this time I went to the doctors for my yearly check up (12/11) and told the Dr about my symptoms. She did a pregnancy test there and again neg. Next day did blood test also neg. but found out that test measures the same levels as the urine so of course it would match since they were only a day apart. Pap test and STD test all came back fine. An ultrasound was scheduled cause during my exam my pelvic area was tender to touch. The night before the U/S appt (12/30 around 10pm) I got my period. It was suppose to come on 12/28. Had the U/S and with a quick glance said she didn't see baby. If I was pregnant I would of been 6 weeks and 6 days from the conception date so I'm sure they would of seen something if I was. After the quick glance for the baby she went back looking at my ovaries and stuff. She said everything looked good but would get the final results next week. Now back to this period that I just got the night before the U/S. This period is lighter than normal. So light that the last 2 days I could of worn a panty liner from the night before and also the whole following day and would of been fine with nowhere close to having any leaks. Not like my normal periods. Still getting breast pain, slight nausea, back pain, and the feeling that I'm getting my period, that from the looks of it is ending today(1/4). Any idea on whats going on with me???
