I woke up at 4 AM feeling so nauseous and with a bad stomach TMI like when you have diarrhea. Went to the bathroom and made myself throw up a bit, washed my face with cold water and I went to sleep like a baby. I'm pretty sure the bread we ate last night was raw enough but I don't know if it was that. It's been a week and a half since I had sex. Checked the condoms and none was ripped or anything. I was also in my day 6 or 7, which is after my period and far from the fertile window. My mom also got nausea and an upset stomach but she doesn't know why. I don't have any other signs... any possibility? When can I test?
