😅 I may have fucked up?

So I'm late. And a teeny bit concerned. I've got a 19 month old and decided to go finally have some fun, being a single parent. On the 25th and the 28th I had intercourse minus a condom. According to my body and calculations, I would have ovulated the 22nd and my fertile period would have definitely been over. Also I can usually feel when I ovulate and it did coincide with the time. I know, it's dumb, but we didn't use any form of protection. He also didn't orgasm but there was a lot of precum, which leads me to where I am now. For the last 3 or so days, I've had moderate spotting (enough to where I thought I started) and now it's pretty much just slightly pink and discolored discharge. Today should be when I start and nothing yet, though it's still the morning.

I know taking a test would be the smart option haha. It's also not the end of the world if I AM pregnant, but I would prefer to have waited a few more years (lesson learned, I know).

I might also be psyching myself out or stressed because things have been a bit hectic lately.

Definitely not asking anyone to diagnose me or tell me what's going on, I know that it's impossible over the internet. Anyone have any thoughts or similar experiences though?
