Heavy Periods + Adult Diapers?

This is my first time on birth control and I’m on the part where pills are just the sugar pills (where your supposed to get your period) I haven’t been taking them because the box said that you don’t have to take them because they are just “reminder” pills. The first few days my period was so light I didn’t need to where a tampon or pad but now my period is so heavy that the second I put on the largest pad I have, I feel like I’m bleeding through. I was wondering if anyone has had a heavy period like this and if they’ve used adult diapers for this problem for over night? Honestly I’m so close to buying some for just over night so I don’t have to wash my sheets every night. Please I need advice!!!!!
