I have to spill it !!

I want to buy ovulation test, 1 to actually know when I ovulate. And 2nd reason is so I know when I will get my period.. I'm sure this is stupid. Last month I got so sick after my period! I did notice some watery CM but not like EWCM. I did have sex 1 time during my fertile week (pull out method) but you never know! Last week or so I've been cramping, feeling very tired, peeing a little more than usual. So I'm just thinking " is this period symptoms or pregnancy symptoms "? Lol shit! My period isn't "due" in about 4-5. I kinda want to test, but I'll probably wait another 3 days(if I can lol) to take a pregnancy test.. hoping for my period to not show🙏
