Hey guys I feel like absolute shit. I think I've got the flu. Is it possible to get the sust flu this late in my cycle, I'm going on week6. I was under the impression that if I was going to get it, it would be in the first few weeks. Anyways, I am dead tired, my back is killing me, and I can't sleep bc of the damn cold sweats. Does this sound like the sust flu or do you think it may be just coincidental?
