Hello, so I'm not sure if I'm pregnant but I'll give you the low down. My last period was sept 29 and I Ovaltined Oct 13 my boyfriend and I had unperfected sex Oct 11 and again Oct 17 and through the rest of the month. My period is two days late. My nipples hurt and my stomach aches. When I put a little presser on my lower abdominal it is a little painful. I'm more tired than usual even when I get a 8 hrs of sleep. I have back pain and don't have any discharge. Also a little bit of nausea and noticed headache more frequent. Could I possibly be pregnant? Should I take a test tomorrow morning or wait till Tuesday?
