Still in it?

Hey ladies! I don’t menstruate normally, once every 3-4 sometimes 6 months, so I started tracking some things to help get pregnant. I don’t temp which probably should have been the first thing I did 🙄🤦🏻‍♀️. I did however start taking ovulation test and I got a smile on the 4th, had sex 24 hours prior to the positive but boyfriend was hunting when I got the positive test so we didn’t BD until the 7th again. I was supposed to start AF today and first I got pink spotting and figured I was out. 😔😥 BUT now it’s brown and still just when I wipe. I took a test, looks negative but is it possible I’m not quite out yet?
