A childhood belief about periods

When I was about four, I noticed that there were these things that were wrapped up like sweets, but shaped like pills (well, to four year old me, anyway) but they were huge for pills, and I didn't know how you could swallow them. Somehow I knew they were Mum's, not Dad's. I think I assumed they were either pills that only grown-up women got to take (taking pills seemed like a much more interesting activity when I was four, probably because you're not allowed to take many) or that they were sweets taht were for grown-up women only. I think I knew what Lillets were by the time I was 9 or 10, but I don't think I connected tampons with these weird pill things for years later. I didn't still think that that's what they were, it's just that I didn't remember my old belief and connect it with the tampons for a while.
