Oct 8 EDD. FTM

Hay, familiar yan sa akin! When I was around that time, one of my mum friends had the same complaint, parang nerve pain yung sabi ng OB niya, super common sa third trimester especially pag umaapak ka ng hindi tama or binalik ang weight distribution. The "lamig" feeling mo sounds like it could be ligament stretching or pressure from baby's position na nag-irritate ng nerve, pero since nag-start siya after a specific movement, I'd really suggest checking with your OB just to be sure, better safe than sorry talaga, lalo na FTM ka pa!
