Mama, I'd really encourage you to talk to your OB or go to a clinic soon, they can give you the proper guidance based on your situation, okay? I get the worry, pero honestly, timing and prevention methods can be confusing, at kailangan mo ng medical advice, hindi lang internet input. Your doctor can assess your cycle, explain your actual options, at tulong ka properly. Better safe than sorry, lalo na sa ganitong bagay. Hugs, go see them soon, ha?
