So I had unprotected sex about 3 to 4 weeks ago. And for the last 2 week's I've had bad head aches, and starting yesterday I started to have sore breasts. I've felt nauseous for the last 2 weeks as well. I normally start my period around the 19th-21st of every month and I haven't even cramped. My belly is bloated. Could I be pregnant?
Yes, go take a test.
