Big tummy..anyone else....??

Well, I'm not really trying to conceive, but I have an issue that's bugging me.

My stomach has looked like I'm pregnant for a few weeks now. Boobs are bigger and slight sensitive at times. I sometimes wake up with headaches and if I don't then they come on through out the day. Haven't had my period since december, which skipping months like this is pretty common with me lately because of an issue. I'm pretty certain I'm not pregnant. I wanted to know some possible answers before buying one.

I greatly appreciate all your opinions.

😊
