Hello, since last Wednesday I have a cold, I had a cough and subfebrile state. On Wednesday and Thursday I ate little, on Thursday it was a total of 2 rolls and some dinner) On Friday I fainted, it seems to me that from stress due to exams, a small amount of food (in the morning then I ate half a roll and the day before practically nothing) and illness. I still vomited that day. From that Friday I started to eat more, but every time I get out of bed after a while I feel nauseous, when I lie down it's all right. When I get up, I feel like eating and I feel very nauseous. I haven't vomited since Friday. From today (Monday) I take the antibiotic azicin. I would add that I also take Vines birth control pills. What can cause this nausea and how to fight it? Is it the fault of the cold? Could these be symptoms of pregnancy? (I protect myself regularly, the last time I had sex with my partner was on May 8 and it was 2 days before ovulation, my partner came inside, but I take medication regularly.)
