Hi mama! Honestly, spotting or delayed period while on pills is pretty common, a few of us mums have experienced that too, especially pag baguhan pa lang or pag may missed doses, pero since you're concerned, better check with your OB para ma-rule out kung normal lang or may ibang nangyayari. Daphne is reliable pero every body is different, so don't stress too much muna but do reach out to your doctor agad para ma-guide ka properly! Keep us posted, okay?
