Hi nina. I started femoston 10 days ago... Very scared too.
I am considering mirena, but am scared about pernenancy of it. I like trialling this first as I'll get 2 weeks without prog, so see how I react to the increase in estrogen.
Are u starting fenoston 1/10. Or 2/10? I'm on 1/10. Good luck. Love to follow how it goes for u. X
