Guys I need major advice and help so I have very irregular periods as you can tell!

My last period was September 19 it was a normal period all my period are normal it’s just my cycle length that’s messed up!

But!! On October I started ovulation and we are trying so we did it but then I missed my periods for that month, then something happened that’s has never happened before!?

I started spotting on November 5th and didn’t stop till the 9th but the whole time I wasn’t enough to fill anything but I was just when I wiped, I’ve bent nausea and idk what’s going on!!
