I can't pinpoint the actual days I had sex. But pretty sure it was around ovulation. I'm on the pill so we don't use any other protection method. Last week I've been experiencing very light spotting. Frequent indigestion which makes me feel nauseated and I threw up one after eating a greasy cheese burger. One of my nipples is slightly tender and I've been kind of crazy lately. My period is supposed to be next week. Is it too soon to tell? Advice?
