It could be bloating, constipation, pelvic girdle pain (although that’s quite early), uterus expanding etc. If you’re concerned I’d recommend contacting the midwife advice line ☺️
It could be SPD
I had these for 3 days last week. 20+ weeks. Especially after peeing. It’s fine now
Hmmm no it maybe ligament pains- your uterus expanding to make room for the baby. Baby moving at this stage feels completely different and soft. Like a butterfly 🦋 flaffing inside you 🩷
