5 days late

I'm 5 days late.. but I feel as if it's next to impossible for me to be pregnant. According to glow and the <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">period tracker</a> app I use my fertile window was from June 13-20 and my ovulation day was the 17.

My hubby and I had unprotected sex on the 22nd ish (late night) but he did not ejaculate inside of me. I know you can get pregnant from precum, however combined with being outside of the fertile window that's why I think it's nearly impossible.

However, now I'm 5 days late and not on birth control. I have regular periods that last 4 days..

Should I test? thoughts? Not really TTC yet, but would not be opposed to being pregnant.

**was extremely emotional last week leading up to what was supposed to be my period. Now I'm just tired. Also I've had this weird feeling in the middle of my uterus for the past 2 days.

UPDATE: Tested and got a BFN. I'm going to wait a couple of more days and test again in the morning or see if AF shows up.
