Early pregnancy symptom?

Keighlen
I know women don't usually have these kinds of symptoms until after they know they're pregnant. I just would like to know. For the last couple days I have been feeling slightly nauseous almost all day. It's not super unbearable, but definitely not normal. And I'll notice it a little more after I eat. Also, my husband and I just had sex (sorry tmi) and it was slightly painful. It almost felt like my cervix was getting punched inside me. And even afterwards just sitting down watching tv, my lower abdomen still feels kind of uncomfortable. I've had a little bit of cramping every now and then also. My period is not supposed to start for another 8 days. Did any of you have any early symptoms like this? Or am I just sick and getting my hopes up?
