I have been nauseated badly to the point of throwing up for over a week. I get headaches as well but not to much I did miss my period this month well I'm a week late but I had surgery in march and had an ovary removed no longer take the meds and felt amazing till last week the nausea comes and goes.i also am hot and cold allot it changes fast and I'm sleepy most of the time no matter how much I sleep. I dont know what it is or could be I really have been avoiding a pregnancy test because I feel it would just be disappointment I miscarried in march not even 2 weeks later had the ovary removed. Any help or insight would be greatly helpful.
