Im sorry i cant help you because honestly i never heard of that, but just wait and take the test but if your really concerned the e/r is always avail. goodluck.
Pessaries can cause irritation, especially if they are not fitted properly. I assume you have one in place to help a pregnancy stick. Is your physician a fertility specialist? I am not sure if there is a particular type of pessary utilized in pregnancy but can dig into it if you like (this forum is for pelvic organ prolapse).
I have cystocele, rectocele, and uterine prolapse. All of them in the 2nd to 3rd degree. That's why I wear a Hodge. I'm not wearing it specifically to make a pregnancy stick, just to be able to function normally. However, there's not a lot of guidance out there as to wearing one during a pregnancy.
Thanks for the details, I'll send an e to a contact I have at Cooper Surgical to find out what I can about your scenario. Hang in there, may take a few days.
My contact said that you should question your physician about why a Hodge rather than a Gehrung (a Hodge is used for incompetent cervix after conception). The irritation is probably just related to the size/type of pessary not being correct. (It often takes a couple of fittings to get the proper size pessary.) If your physician is a gynecologist, you might want to touch base with a urogynecologist to see if you can be more properly fitted with the correct pessary to suit your needs.
