Could this be it???

Guys, so I’m still breastfeeding my 1 year old. Luteal phase normally 5-6 days. Wel I’ve cut down to feeding only at naps/bedtime/overnight. I’m currently 7dpo, no spotting (which I normally have). Period like cramps and increase in CM. Its probably just pre warning that AF is about to start, I’m obviously hoping for BFP but if not at least my luteal phase has got longer. Just wondering if cramping, and increase CM from 5-7dpo has been a sign of pregnancy for anyone?
