Ah sis, I feel you, super stressful yan, lalo na when you're unsure! So honestly, pills can really mess with your cycle, especially in the first few months kaya hindi ka mag-isa dito. A few of us tried different contraceptives and ang delayed period ay super common, pero I get why you're worried pa rin, eight days plus five PTs is a lot! The thing is, even with serum tests (which are more accurate than home PTs), sometimes ang timing lang talaga, false negatives can happen if you tested too early in your cycle, or the pill just threw everything off. One of my mum friends had the exact same thing happen and after two weeks the period came na lang, walang baby. But since you've done multiple tests na at delayed pa rin, it's really worth a quick check-in with your OB just to be 100% sure and get clarity on kung ang pills talaga ang culprit or if something else is going on. They can do proper follow-up tests if needed at mag-adjust ng contraceptive if kailangan. Praying it's just the pills doing their thing, but don't stress, your doctor will sort it out!
