Help!

I don't have anyone else to really ask so appreciate all input :)
I am five days away from my period, but about the last week or so I have been super naseus, back pain and lower abdominal pain. The last two days I have been super horny (hope not tmi) and feel like I have to pee constantly... since so many menstrual signs and pregnancy signs are the same I was curious if anyone had any input if this I pregnancy symptoms or not... I don't want to really get my hopes up.
I have PCOS and have been working out over a month now and adjusted eating habits to help lose weight to conceive
