Last night I used a "regular" pad- Always Infinity brand because I grabbed it out of my basket thinking it was a natural one. I had gotten rid of those long ago but that one somehow stayed in the bathroom cabinet. anyway- i started to have violent itching  after about an hour. I changed the pad to a cloth one i had and the itching all but stopped. I was just amazed at that quick awful reaction!! I am using cloth again today because the pads always irritate me. Wish there was a better option! I've tried the diva cup and did not like it. I like the instead cups but not in the beginning of the period when it is heavy. Just wanted to warn you to  be vigilant about the natural pads. I thought that was someting that was more of a "cumulative" effect thing but it was an immediate reaction.
