I'm confused

Juanita👼👼👶👫💙👣 • 2 miscarriages under my belt and on my heart. Currently 39 weeks pregnant. God is good!
In confused as to why my tests are so light and glow says I ovulated the week of valentines day that would make me at least 2 weeks past ovulation, I've had light cramps itchy boobs heavy feeling boobs vivid dreams period is 5 days late. Everyone is posting at 9/10 dpo and theirs are darker than mine at 14 dpo. No bleeding at all I have been having an upset stomach every time I go to use the restroom I have diarrhea sorry tmi. I'm gonna test again on Monday but should I be worried?
