perimenapouse and vagifem

Hello,
I am 52 and I am perimenopousal. I had my last period 65 days ago. I have VA with a burning sensation, and my vulva is really irritated. I am married for 20 years but sex is out of question right now (to tell the truth it had been almost a year, no libido, painful intercourse). I am in Canada, I went to GP and they ruled out BV, yeast and STDs. She put me on vagifem. Everyday for 2 weeks and then twice a day. On the 4th day I started to experience side effects like palpitation, nerve tremour, nausea, bloating. I don't feel very very dry down there but this burning sensation makes life a misery. I don't have itch. I read many good things about vagifem an users are generally content. All the over the counter and natural products made me somehow uncomfortable. I want to be on vagifem. What happens if I skip the 2 week loading period and use it every 3 days? I think I still have some estrogen in my system, do you think it my cover the initial loading period? Or the loading period is absolutely necessary. I would be most grateful for your opinions. I may see an OB but in this country it will take at least 4 weeks if I am lucky.
