Briony - No worries. My GP wasn't very happy with me staying on the BCP till I was 54 it has to be said! However, I have MS and there was quite a bit published demonstrating the beneficial effect of oestrogen on MS (pregnant women don't get relapses). Armed with this information my then GP kept me on the BCP till I was 54, however, this son of satan wouldn't give me HRT. It wasn't till I'd been off the pill for 6 months, had consistently high FSH readings, oh, and had a spectacular MS linked, double black eye creating fall, that I found my current GP who prescribed Evorel Conti which has helped massively.
You ask did the risks worry me. Given I'd taken the BCP since I was 15 I have to say no. When I first stopped taking the pill, I really liked the fact I wasn't clogging my body up with artificial drug/hormones. However, I changed my mind after 6 months of continuous hot flushes and the face damaging fall.
