Mild cramps no period strictly breastfeeding

Taneesha

Hey mamas so I posted a week ago if it was possible to get pregnant with no period and strictly breast feeding my 3 month old. Hubby n I had a fun night finally lol n now I’m anxious. Anyway I’m having mild cramps. Just wanted to see with some mamas experience if it’s just normal to have random mild cramping at 3 months postpartum? It’s been a week since we had sex unprotected. I literally thought no period and BF I couldn’t get prego 🥴 so is cramping normal?
