I ended up at the ER due to severe stomach pain and dizziness and they took a blood and urine sample from me. I didn't think pregnancy was very likely the cause but I thought it might still be possible. They came back and told me that everything was fine and that I was just experiencing an abnormally painful ovulation process or something like that. I've had two normal periods since then but the third one I had lasted almost a week longer than normal. I was wondering if pregnancy could be causing it and if the doctors just didn't tell me the results of the samples I gave them. The last days of my period were heavier than spotting but still very light and it's partly brown and partly bright red. Please help!
