Anyone been on the pill?

I just had an ah ha moment - I've been lurking on this thread and another one thinking, no I don't have any problems on the pill. Then it clicked - I'm on the minipill and seem to have difficulty shifting weight while I'm on it. I was on it for 8 months while BF and struggled to lose weight, then went onto the normal pill (+ made some diet/exercise) and was doing really well then my GP told me I had to go back to the minipill and I"ve recently been thinking my weight has plateaued (and maybe gone up a bit?).   Will keep an eye on my clothes and talk to my GP next time I'm in.
