I don't know whats going on. I've felt sick now for about a couple days. I've only been sick during the night tho. My period tracker says I should start November 24th. I an my fiancé have had unprotected sex for the past 5 months he's told me he always pulls put before cumming. I just don't know what's going on I feel horrible.
