Weird I know but....

I know this will sound a bit weird but, I was a day late with AF (what I'm assuming is AF) and she arrived in the wee morning hours on Saturday (the day of my friend's wedding😡). However, I've just been spotting since it started with a lot of cm. So, earlier today. I took an opk test (just for fun) and I got a line😱. I never EVER get lines on an opk test strip. So I then  ook two htp test and got nothing (I think). Can anyone make heads or tails on this? So confused....
