So my youngest is 1. I breastfeed her. Exclusively pumped. I’ve only had 3 periods since having her. Last was Dec 26th. And before that 2months prior. So I’m in no way regular. Wednesday. I had some pink tinged discharge when wiped. Okay cool, thought just ovulation maybe. I took a ppl and not quite positive but close so figured I probably missed it as we aren’t really testing like that. We’re easing our way back into trying, Thursday, I had a bit more but more when I wiped and not just discharge tinged. Today(Friday, CD 16) it’s once twice been enough to hit my panty liner, been there mostly when I wiped today. Still getting son very light pink when I wipe tonight but today I’ve also just been very crampy. I’ve been taking opks just incase and yesterday they lightened clearly negative. Even earlier today was clear negative test line light. Tonight, it’s starting to look darker again(pic below) so I’m kinda just wondering has anyone had this happen? Why am in spotting and cramping so much?
