These are maternity pads that can be used from the time your water breaks. It's a good idea to have some on hand in case your water breaks as you get closer to your due date, so I don't think you can have too many. M size → Unopened x 2 sets (20 pads total) L size → Opened x 2 sets (5 pads total) I am also selling baby items. Please comment if you would like to purchase multiple items together.
