After using Insteads, I can hardly stand to go back to pads and tampons!! Tampons would hurt me if I used two in a row, and it's like my body just.. hated them. My vagina would clench up and I couldn't get it all the way in, so it ended up being REALLY uncomfortable. Come to figure out later, they were causing me cramps!!
And we all know what pads feel like... especially if you have a heavy flow like I do. Yuck!
With Insteads, they say it's safe to leave them in for up to 12 hours (on a lighter day) but no matter how heavy, it lasts twice as long as pads or tampons (which is true). However, sometimes when you take it out and it's full, some blood will gush out, but if the toilet is right next to the sink you can just have the water running and rinse it right off.
The only other problem is that they are a lot more expensive. But I don't really consider this a problem because if they last twice as long, you only use half as much =]
All in all.. they are wonderful!!
