Input needed please.

I'm new to this, me and my fiancé have been trying for 2 months. I don't wanna get my hopes up because I was positive we conceived last month because I had the cramps and tender breasts, but my period only lasted 4 days vs the typical 7 days. Well this month my breast are tender, I have a funny taste in my mouth( I'm not sure when people say a matallic taste) and I had bad cramps a few days ago, I'm constipated, had gas, and I have thick/sticky CM. I've been overly tired and by lower back has been killing me. My AF isn't due for another 6 days. Could I just be getting my hopes up, or is there a chance this month could have worked? Please I'll take any kind of input!
