I've got both primark and Wuka period pants and they're both great, only I find the primark ones don't wash as well.
I used a cup for yeaaarrss prior to pregnancy. Post pregnancy it literally doesn’t work anymore. Apparently a very common issue as the shape of your cervix never goes back to normal. So I would be careful splashing out on any cup/disc! I’ve had to revert to tampons which I hate using (economic and environmental reasons)
flex disc!! they make disposable ones or reusable. I love them!
I use the period pants from primark & M&S if you’re from the UK. and they’ve been so good for me :)
