I think I might be pregnant but it's far too soon to test

I have been pregnant 6 times... one abortion when I was 15 and 5 were miscarriages. With every single one I got a sore throats a few days before I got a bfp.. well I'm a week away from af.... I have been super tired, nausea a lot, loss of appetite, extreme headaches I've noticed I've been going to the bathroom more, af cramps, a pressure feeling in my pelvic area, and my sore throat.

Now I don't know exactly when I ovulated exactly so I can't tell how many days past ovulation I am.. what do you ladies think though? Could I be pregnant?
