I've narrowed it down to Yuuki, Ladycup, and the meluna, but I think I have a high cervix, since I have to put my whole index finger in to feel it, which is about 67 mm, or 2.6 inches. It's not much lower on my period.
I'm 16, and a virgin (although I don't think I'll be one for much longer), so I'll be getting a small.
Ladycup seems like a good brand, but the holes are a bit lower, so it can't hold that much. My flow isn't very heavy so I could probably deal with this.
The Yuuki seems good, but I've heard a few bad reviews about their company, and I'm not entirely sure they can be trusted.
The medium meluna seems good, since I think the small will be too small, but the medium is kind of short, and I'm not really sure how well this will go with my cervix.
And cost is an issue, so the last two I think are the better options cost-wise. Unless I buy on ebay, and I don't really want to unless I have to.
