Not feeling so well

Af going on 3 days late and I haven't been feeling well at all... I was working out at the gym everyday for the past month and then since the day Af was due I have barely had any energy. I have cramps bloating and pressure and it kind of feels like an upset stomach... plus last night I went on a short walk with husband and was completely out of breathe... I took a pt but idk I think it was faint but I posted and 50% said they saw nothing... I'm so confused :(
