Some lesser known variations might work for you misree : not the firat ones people reach for but may work for you? If any sound interesting go to your local family planning clinic rather than your GP who might not be as familiar with these....
NuvaRing. It's like the combined contraceptive pill (so NOT like the injections), but in the form of a runbee ring about 5cm in diameter that you insert like a tampon once a week. Used a lot in France, apparently it's quite comfortable and you have three weeks of a ring in then one week without to get a withdrawl bleed.
Combined pill in patch form: again appllied once weekly. Three weeks of a patch then one week off. If you're able to have the combined pill, don't want a Ring, but have forgetting problems the patch could be ideal.
Diaphragm or Cap. Not the most reliable method but is a good barrier alternative to condoms if you are able to get uaed to it with a bit of practice: it's a bit of an art to put em in and they have to be used every time in advance of sex with spermicidal foam, and left in for 6 hours afterwards. If you go for one of these the clinic witl fit it for you and train you how to use it.
Condoms: an oldie but a goodie. femidom: sex inna duffle bag compared to a condom, but it takes all sorts.....
Does any of those sounds possible?
