Hello. I started on Evorel Conti patches just 3 weeks ago.
After 6 days I too started with awful cramps. It was just so painful.
I ended up phoning my GP, who suggested I cut the patches in 1/2 for a while, to let my body get used to them.
That stopped the cramps after just 1 day.
I'm speaking to him tomorrow, so I shall ask him how long to stay on 1/2 a patch before increasing.
So I think, yes, its normal to feel side effects whilst your body adjusts.
I'm going to persevere for at least 3 months, as that seems to be the general advice.
Good luck and I hope things settle for you too.
