Confused / hopeful

I feel like I’m on borrowed time right now.

My cycles have been short lately (27 days) and I always O around CD17/18/19. So super short on the back end. I’ve been getting my period around 9dpo for months. This month is different in a lot of ways. We could only bd on the day I got a + opk but it only takes once right :). I’ve also had next to no symptoms. I normally have sore boobs, bad cramps, acne etc. This cycle almost nothing until 5dpo when my nipples started to hurt and I have been dry congestion and a ridiculously dry mouth. yesterday I had some dull cramping, light pink spotting (twice only when wiping) and I started crying for no reason when my son was pouting. Today 9dpo I had some light brown spotting, again only when wiping but no cramps nothing. It’s almost bothering me to not feel anything.

Anyone experiencing or experienced something similar?? Or just as confused as I am. :)

Thanks
