Scared to test!!!!!!!! Need advice should I wait??

Okay so I have a very irregular period I have actually been trying to lose weight and it had become regular I have 3 period apps and 2/3 say I’m 8 days late for my period the Flo app says my period is due in 4 days so I’m waiting to test until then. Around the time two of my apps predicted my ovulation I had 3 days of ewcm so I’m guessing they are a bit more accurate but I’m unsure. I’m afraid to test too early because usually when I do Aunt Flo comes the next day but around the time of my predicted ovulation I also had spotting not a lot literally two dots on one wipe and it was gone around that time I was very constipated I had cramps every night for a week and I’ve noticed other symptoms

I can smell my son pooping and peeing in his potty from the front room and I got a whiff of some bbq sauce that made me feel nauseous also washing dishes is the worst

I have been nauseous on and off one day I even puked twice sorry tmi

My lower back has hurt everyday since I noticed ewcm

My boobs have went from tender for a week to my nipples being sore this week

I’ve been extremely tired

I’ve been light headed/dizzy on and off

Last straw was after BD I am now very uncomfortable not really crampy but a slight soreness in my pelvic area I felt it a bit during and it wasn’t bad but definitely caught my attention

Also tmi!! But for about two weeks I’ve had creamy white cm

Everything is telling me to test because I just feel it but I’m afraid of disappointment
