How long does your first menses last

You mean the bleeding after birth? Mine was quite heavy for my previous pregnancies. Whenever I stand up or lie down blood will drip and I will stain my clothes. Back then the largest size for normal pad is not like today so I relied more on maternity pads. But they're uncomfortable as they stick to your skin unlike the normal pads. Gave birth again this year on Feb and I was given clot jabs. Amazingly my bleeding was so, so much lesser than what I had before. Before birth I bought the largest size pad but then I didn't quite use them but the normal size pad with wings. Just buy the normal pad that you normally use but get the big size and just in case the normal size too.
