Chickbits - Hello and Welcome
Don't panic!!!! Initially you may get a few stomach cramps or even a bit of spotting but this is normal. The amount of oestrogen in Vagifem is very, very small and, in fact, for many of us too weak. The absorption into your system is really, really negligible and the side effects in the leaflet are the same as for full HRT which is silly!!!!
Many of us on here are using Vagifem and I'm finding, after 3 months, I'm still getting those terrible burning/ Cystitis type symptoms - its' truly horrible. It can take many months for the whole area to come alive having been starved of oestrogen but I'm hoping it will eventually work. I was on full HRT for many years thinking it was enough to keep atrophy at bay but now realise I needed local oestrogen as well.
There are a few threads that cover this issue so dip into these and soak up the info. I am trying D-Mannose (teaspoon everyday) on the advice of the COB foundation when I rang them. This is supposed to help reduce the chance of infection taking hold in the bladder. Time will tell if this helps as well.
You could also use a gel like Mulit-gyn Actigel to help keep the vaginal area more acidic and reduce the risk of bacteria taking hold and speeding - I find it quite soothing after the initial slight stinging.
I'm sure others will be along with thoughts and advice. Keep us posted about your progress.
