Sis, this is really important, please talk to your OB or go to the clinic ASAP para sa tamang timing at instructions, lalo na't hindi ka pa nag-regla. Contraception timing depends on marami pang factors na kailangan i-check ng doctor, especially postpartum.
I know it's confusing, lalo na first time mo at walang explanation sa ospital, pero ito talaga dapat straight from your OB para safe ka. One of my mum friends had a similar concern and her doctor explained everything once she asked, wag mahiya! Congrats sa baby, and take care of yourself.
