It seems like no matter what I put in my vagina for menstruation, I start to feel sick at some point. The only reusable menstrual cup I've tried is a Lunette. I have seen my cervix with the aid of a doctor once, it's slightly recessed. I wonder if that's why I can't get a suction on it with the Lunette. If I get the Lunette positioned in a way that's comfortable, I always feel nauseous within an hour OR it gets dislodged and makes me feel like I need to pee. I've always had the same problem with tampons too, I can only wear them for a few hours at most no matter how heavy my flow is before I feel nauseous. The best thing I've used for internal menstrual coverage is Instead Cups. Usually I don't feel nauseous until the cup is full. I have to give my vagina an ~8 hr break between wearing the Instead Cups otherwise I'll get nauseous again upon reinsertion. Usually, I'll try to wear one overnight and use pads during the day.
Recently, I bought some sea sponges to use as reusable tampons. They're intended to be inserted high, close to the cervix, not in the vaginal canal. I don't feel them when they're up high, but of course, I end up feeling nauseous within a few hours. I wore one for a few hours last night until I felt sick, wore a pad overnight, wore an Instead Cup for my bicycle ride to work this morning, but had to take it out right after getting to the office because I was nauseous already.
As far as I can tell, this has something to do with the sensitivity of my cervix. Is this something I might adjust to over time if I just try to power through the nausea, or does anyone else have a problem like this?
I use cloth pads for menstruation usually, but they don't work well for bedtime. I can only sleep on my side during my period or I'll leak :(.
BTW, I've posted previously about DIV and still have not found an effective treatment method. The itching has been bearable lately so I'm mostly just trying to ignore it :(.
