Severe Cramps While Using Tampons?

I have always had bad cramps during my period and I just had a pap test and pelvic exam done the end of September, and everything was normal. I use "regular" tampons and I have a pretty heavy flow for the first couple days. Just wondering if anyone else experiences strong cramping while using tampons? I also have IBS which causes stomach cramping which gets worse during my period. Sometimes the cramping is so bad I almost vomit. I am 24 years old and I don't leave them in any longer than 4 or 5 hrs. Thanks for the help!

Thanks Zoopy. I only seems that it is the first two days that the tampons seem cause an adverse effect. It does seem to make the area more sensitive. I really appreciate it! Glad to know I'm not the only one. The reason I still use the tampons during the first couple days is because my flow is quite heavy and i feel more secure using the tampon than just a pad.

I used to get vomit inducing cramps whener I got my period as well though it was not related to tampons. I never use pads I feel more comfortable with tampons and I use the "super" tampax ones. My period pains are almost gone ever since I went on the pill (and even now that I stopped it), they are definetly not making me puke any more! If you think tampons are making the cramps worse i suggest you stop using them, I have friends who cannot use tampons for the first two days of their periods because the pain makes the area too sensitive. I would also suggest taking pain killers, it took me a while to find something strong enough to work for me, nimmesulide helps me alot! But you should consult with a doctor or pharmacist before taking anything.
Good luck!
