Cherryblossum, I just wanted to recommend Clindatech also.

I sympathise with you as I never got acne as a teenager either but as I got older I began to suffer from hormonal acne (big sore blind pimples on my chin) and the only thing that fixed it was the pill called Diane 35. I got the odd spot while I was pg but like you, after the birth I got acne terribly again. I asked my Gp for a prescription for Clindatech and I have never looked back!
