Lots of gas and boob pain..

Yes I said it! Lol I have been so gasy and I feel like my bra is just gonna pop out!!! Not to mention I've been crying over EVERYTHING! The crazy thing is, I haven't taken a test yet! I was just curious is this was any one else's side effects at first. Oh and my back is killing me! I can't walk upstairs with out taking a break and when I get out of a chair, boom! Back kills!
