So... Baby, yes or no? HELP!!!

Hey everyone!! about a month ago my husband and I had sex. (He came inside me) I'm on the pill, but we've been discussing getting pregnant.. So If I am it's not a bad thing at all. I'm just wondering if this sounds like I could possibly be pregnant?? So... A month ago we had sex, and about 5 days later I started spotting. But the spotting lasted for 6 days, wasn't my period at all! I also had really bad cramps with this. I'm still not due to have my period for another week according to my pills; however, I've been having the cramps, feeling very bloated constantly and needing to pee a lot more than usual which is weird for me? Also, every time I've eaten something these last three days I've felt nauseous and feel like throwing up. I didn't think of pregnancy until I realized how terrible I've been feeling lately. I know most of the answers will say take a test... But I'm wondering if my symptoms are signs of pregnancy or just from me thinking they are? Thanks!!!
