Aches/pains

Jaci

My period isn’t for about another two weeks but here recently I have had bad lower back pain, mood changes, high appetite, and more tiredness. Should I be concerned? Just wondering because I’m new to this. Also heavy liquid like discharge often, mostly everyday. I’m also assuming I was just ovulating? But I probably only had sex 3-4 times in a couple days to a week or a little over a week ago.
