LEAKAGE HELP

SO whenever I lie on my back or sit on my bed I seem to leak really fast-even if not full- I always wear little shorts and it goes through those too!!

I’m sharing a bed so gotta stop leaking onto the bed but what’s the best position to sleep in? I try and stay on my tummy

But this always seems to happen

I- this was literally after lying on my back on the floor for 10 Mins! As u can see the pad back there isn’t even full!!! It’s leaked through my clothes where there is no pad

Grrrr

Help!

I feel like I can’t even sit on my bed without leaking
