The fetus can hear sound at about months after conception.

Around week 16 of pregnancy, it’s likely that these structures are well-established enough for your baby to start detecting some limited noises. Some of these are sounds that you might not even notice yourself — the gurgle of your stomach and whoosh of air in and out of your lungs. Over the next few weeks though, your baby will hear more and more of the outside world. By week 24, babies have been shown to turn their heads in response to voices and noises.

10/10 recommend bring pads/tampons with you no matter what. im 16 & i’ve had mine since i was 12 and they’re still it regular, but id suggest using the glow app, many women use it for fertility reasons but i use mine specifically for the period tracking portion and it guesses when your next period will most likely be for the next two months. i dont believe theres any way to delay your period, so id say hope for the best but make sure to bring all of your stuff just incase. have a good cruise!
