I know alot of women post on these sites about simular topics. But I have never seen one about my situation exactly. I had sex on March 15th. My period normally comes the last week in the month, but it came on the 19th. I normally have light periods, but this one was rather heavier. after that week, I began to feel a nausea feeling at the same time every day and soon progressed to mltiple times during the day. I also have been having headaches for 2 weeks on one side of my head MAINLY. My breasts have gotten bigger, and they feel fluffy. They also hurt on the sides. This continued and now its the 23rd of april and my cycle has not came. On the 21st I felt as if I was going to urinate on myself and when I went to the restroom I discovered a light bron discharge in my underwear. I wiped 3 times and it never came back since. The following day I went to work and had a tight feeling in my chest, well my uper abdomin, and it went to my back, shortly after I began to feel like my cycle was about to start and this continued up until the next day. I took a urine test at home and It was negative. I went to the doctor and told them my problem. They took a urine sample and it was negative as well. The drew blood, but I am not sure if they ran an extra test for pregnacy since they had previously taken a urine test. After They ran tests for stds and hiv and other things, they informed me that they could not find any problem. But there has to be a reson for whats happening. They gave me an iv for dyhdration, but now I feel even more weak than before. Can some one give me their opinion on what could be happening, even if its not pregnacy. Any simular situations. Please, no post from people who want to ask questions, just really concerned informative people. Thank you.
