Okay so I was switching birth controls and unprotected sex with my fiance and he came is me. I ended up getting my period a few days later and this was about three almost four weeks ago. I've been super bloated, nauseas, extremely tired, super emotional, and my boobs have been really sore..basically all the symptoms I had when I was pregnant last time. Our daughter is three months old. Is there a chance I'm pregnant again..?
