Feeling down

Sarah • Due with my first baby April 2018
Af is due sometime between 10/2-10/4. My cycle is usually 25 days (just regulated in august) but this app says af is Friday and another app says Thursday. I took a test yesterday, 11dpo. It was neg. I've been feeling a little crampy/bloated. I feel like it af and I'm already out this month :/
