I took a first response test on Sunday and it was negative then I took two Kroger test and they were both negative. My last period was December 12th I'm expecting my period in 5 days. I had intercourse on December 28th but he didn't cum in me. We use condoms. I puked today after eating super greasy onion rings I never eat to much grease so I think that is why I puked. Also I had bad stomach cramps after puking. I bought first response and clear blue today I'm taking first response in 5 days and clear blue the 13th of this month. I hope I'm not pregnant everything is to hectic right now. Do you think I might be pregnant? I don't have any other symptoms besides the puking. Idk please help me !!
