Too early?

Back story. I had a miscarriage back in January and haven’t been able to get pregnant since. Well, on 9/16 I had an ultrasound to look at my uterus and ovaries due to me developing a cyst (we were doing a follow up). My OB said I had a big follicle on my left ovary, suggesting I would ovulate within the next few days.

My period was 9/11-9/15. According to my OB. I should’ve ovulated 9/16-9/19. According to Glow, my ovulation date was 9/25.

So I’ve been having light cramps here and there & today I felt slightly nauseous. My period isn’t due for 9 days. Would it even be worth testing this early?
