Monicup Menstrual Cup

This is a silicon menstrual cup and I'm going to try it out for the first time!

The seller described it as 'purple' but it is definitely pink, which I approve of.

The cup has little marks on the side so you can see the volume of menstruate collected.

It also came with a satin bag to keep it in in between uses, which I appreciate.

I have both the large and small size because I wasn't sure which one would work best for me.
I tried the large and it just wouldn't unfold inside of me.
The small one works for me.

On the first day:
I like the E fold, preferring it to the C fold.
I do have trouble getting the cup in far enough though. 
It's like I have a little silicon doodle (the tail sticks out about half way). XD
So far I have not leaked :D

On the second day:
It didn't open when I put it in, so it didn't work, but I was wearing a pad so it wasn't a big deal.
I re-inserted it and it opened properly.
I didn't feel comfortable sleeping with it the first night, but tried the second night.
Second night, it was fine to sleep with.

On the third day:
I just couldn't get it to unfold properly.
I tried multiple times throughout the day :(
It worked well overnight though.

On the fourth day:
I had to take it out midday because of sexy, sexy cramps.

Overall it is a nice idea, but not reliable enough for me to use just the cup.
But it will help me reduce the amount of pads I use, so that is something.

*I have since tried it a few more cycles and same thing. When it works, it is great. But it is unreliable and doesn't always open properly. So I have to pair it with a pad.
It's good as an extra layer of protection, but I can't use it alone.
I think I need a different brand and design.

Price: 3.5/5 ($11.46 each and it is reuseable)

Effectiveness: 3.5/5
