Estelle, didn't mean to confuse you - it's Yasmin that's not prescribed in some countries, not Yaz. Yasmin has same progesterone as Yas but lmore estrogen. In the U.S., it's one of the most well tolerated pills. Risks are higher than first generation pills, but still relatively low. I think it's something like 3 in 10,000 will get a clot without taking any medication; 6 in 10, 000 taking first gen pill, 12 in 10, 000 on pills like Yasmin and I think it was 15 in 10, 000 chance of clot when pregnant (ie highest risk of all). Do check to confirm this. (I'd only trust professional data like this , preferably from the UK medical authorities).
It's a very personal choice and depends on how much quality of life you will gain v the potential risks. For me, I knew it was my only choice. HRT wasn't enough and I was at risk of losing my career, partner and sanity if I didn't do something to help the symptoms. When the consultant said I'd be more likely to have a stroke when pregnant than on the pill, I decided to risk it. However, I fully respect anyone who chooses not to take it. It's a very personal choice. X
