Is it too early to take a test ?

Ga

Hello everyone! So I had my period the 8th of September and it ended the 14th. On the 15-18/19 I had unprotected sex with my boyfriend. This was the first time ever having sex without being on the pill and I didn't take a plan b. He did not ejaculate inside of me and pulled out in time every time. I'm just worried because according to glow, after the last time I had sex I was due to ovulate in 4 days SO ACCORDING TO GLOW I WAS NOT OVULATING YET but other posts about ovulation and pregnancy are confusing me. So can someone please shed some knowledge on me of my chances of getting pregnant given the information I've provided ? Also given that information, my BIGGEST question is would it be too early to take a home test now ?
