17 days late, waiting to do take a test

Hello, I'm 21 years old and 17 days late.

1. I had protected sex on 21st July 2020 which was my cycle day 14(according to glow). He didn't ejaculate inside me and instead finished on my tummy. The semen had trickled down to my thigh and he wiped it off thoroughly. (Do you think if the tissue came in contact with the vulva that could've caused the swimmer to find a way up? 😂)

2. Anyway, I'm on my cycle day 50 and I still have not got my period.

3. My cycle is usually regular, 30-32 days, but ever since the lockdown happened I've been irregular. In the month of May, I was 16 days late but I wasn't worried because I had not had sex in 2-3 months back then.

4. I got under a lot of stress also because of a huge fight I had with my boyfriend and I had also been exercising-high intensity Pamela Reif workouts.

5. I had lots of ginger and ginger tea yesterday hoping to induce my period but I just ended up feeling nauseous this morning.

6. I've just bought a pregnancy test and I am thinking whether it is the right time to do it since I'm pretty late and also if I try doing it in the evening instead of morning, does that alter the results?

What do you think ladies? Pregnant or just stressed and missed an ovulation? Please help.
