Have you tried a menstrual cup? Make sure you wait to use one until sex is no longer painful (I didn't wait that long and ouch!) but then they're great! Get a larger size and you'll probably only have to empty once in the night rather than twice. I also use bamboo reusable pads in case my cup leaks.
I like period pants for night time but PP I have leaked through those, tampon and period pants might be okay if you dislike pads, im looking at getting a new cup now too but just need to do some research 🤪x
I hate pads, but I used to have to do a tampon then large pad to catch if I bled in the night.
