Thanks @seven201 and @Cream123
Gosh I have had the most stressful afternoon trying to take everything in and get everything sorted.
Clearly the gardnerella is resistant to coamoxiclav. The lab has recommended metronidazole which I've got, I'm also going to get some clindamycin. And I'm going to do 7 days of oral metronidazole and 7 days of vaginal clindamycin. If that doesn't get rid of it then I don't know if I'll ever manage to eradicate it. The stressful thing is that gardnerella is a normal part of the vaginal flora and clearly the stuff in me is resistant to at least one antibiotic.
I'm not going to start the antibiotics until Monday. My gp has given me a vaginal swab but I can't do it until Monday as it's Friday night now. The hope is that the swab will pick up the gardnerella and the lab will be able to detect what antibiotics its sensitive to. Hopefully that will add reassurance that the metronidazole and clindamycin will work.
I have has my head all over the place as to what to do next. I think I'm going to tell my specialist I want to go straight into the FET. I'm worried that the longer I leave it the more likely it will become bad again. I'm expecting to start the cycle around 2 weeks on Monday so that gives me a week to do the antibiotics and a week of vaginal probiotics, then I will keep doing a daily vaginal probiotic until transfer day.
@Cream123 I've been taking the vagina probiotic at least weekly and 2 different oral probiotics with the right strains in daily. This gardnerella is clearly not giving it a chance. I guess the only positive is that at least I've got rid of the other dysbiotic bacteria and there does seem to have been lining improvement at a result.
