Hi! If you have irregular periods, it's honestly best to check with your OB kasi mahirap mag-guess ng timing, a few of my mum friends with irregular cycles ended up testing too early and got confused results. Most home tests work best around 2 weeks after you last had intercourse (when hCG levels are higher), but with irregular periods it's really a toss-up, so your doctor can do a blood test instead which is way more accurate regardless of your cycle. Good luck, hoping you get the clarity you need soon!
