Ovulation or pregnant?

It’s only my second cycle or so using glow. According to my fertile window I had unprotected sex five days before ovulation. This was around a week ago. Probably overthinking it but for the past 2 days I have been so tired! Drowsy actually, hard to keep eyes open. Pelvic pain, and I’ve woken up this morning with chest pain. I have been pregnant before and when I knew my symptoms were very tender breasts but was already 5-6 weeks when I found out.

Are my symptoms now from ovulation or is it possible to feel signs of pregnancy really early on?
