Could I be pregnant

I fell pregnant in dec and at 5 weeks pregnant starting getting night sweats I was waking up soaked. I miscarried in feb and still got the night sweats for another week. Anyway been trying hard to conceive since. I ovulated 10 days ago and the last 2 nights woke up soaked in sweat again. Could I really be getting symptoms this early ( my period is due next tues. ) starting to build my hopes up but then keep thinking is it just all in my mind :(
