Heavy Breasts!

I baby danced at the beginning of my fertile window on Medium (7% and 8%) days. Around 5DPO, my breasts felt full and heavy. 8DPO, major insomnia and heartburn kicked in. I’m 9DPO now. My breasts are super full, I feel like I’m cramping or pinching down there, my skin is itchy—especially my scalp and I’ve developed an eye twitch! I usually don’t get symptoms when AF is coming. Anyone have these experiences?
