I’ve been cramping since 7dpo (according to glow). It started out really light but now I’m 12dpo and the cramps are pretty moderate. I don’t ever get stomach cramps for my period anymore, only back cramps, and they never start earlier than 1 day before my period. My period is due in 3 days. If this was implantation wouldn’t it be done by now? I’m waiting until my period is due to test
