just wondering if im the only weirdo!...lol

ok so this might be kinda long! i just want to see if any of this happened to anyone else. i have a 2 year old and with his pregnancy i had no symptoms not even sore boobs as a matter of fact i didn't find out i was pregnant until i was 18 weeks and 3 days i had normal regular periods the only reason i took a test was because i was getting a really weird bump...lol i think i might be pregnant again which i really hope but i think its to soon to take a test. this is whats going on.... i am a very small person and just out of no where i started putting on weight 4lbs in 2 weeks all in my belly an butt, my skin is so dry and itchy, i am staying constipated, I'm tired all the time but i cant sleep, i eat 24/7 i even wake up in the middle of the night to eat sometimes....but the reason for this post is when me and my husband had sex i was not ovulating it was like 2 days before my last period which was nov 1st sooooo could i be pregnant
