I worried about making sure it's in properly too... its a bendy silicone ring so you press your fingers in the middle of the ring to make like a figure 8 shape and put it all the way up as far as it will go. I'll always check that it can't be pushed up further and it seems to just pop into place really well for a simple ring and it's never moved or been bumped. It costs the same as the pill $20 per month. If you get it through family planning centres, its cheaper than a script from the chemist, FPA can give them to you in their centres.
