8dpo anyone else?

8dpo (app predictions) and still have 8 days left until AF. Had unprotected sex multiple times throughout the predicted fertile window. Have had frequent urination for many days in a row including now as well as slight nausea here and there but never actually sick as well as gas and little twinges in lower abdomen. More recent symptoms starting yesterday and today I’ve had a slight burning feeling in my throat and upper chest which I’ve never experienced before and some slight burning tingling feeling in my nipples. I looked back at my log and had logged frequent urination the day before the predicted ovulation day so could that be a sign of ovulation or could I maybe have ovulated earlier than I though? Am I out this month for pregnancy or should I still hold out some hope?
