Did you know ? Or did it sneak up on you.

Hey guys, so I’ll be upfront and honest. I was being quite careless during my ovulation week, having unprotected sex with my bf. It’s been a couple weeks and I’m extremely bloated, gassy, my appetite is gone and I’ve acquired a stuffy nose. Is it to soon to take a test ? I’m kind of nervous I might be pregnant. What were some things you moms first noticed in your early stages of pregnancy? Also I’m 20 if that makes a difference to anyone.
