Help please!

Hi!

So i was on the pill for a good 9 years, came off it last year as i had an op and they put the iud in my for 3 months. Had that removed last November. Started trying for a baby in May. In the last 4 weeks i have developed ACNE. Like fullof acne. Ive never had it before. Im wondering if this might be because the birth control is now out of my system?

Is it possible that its taken this long for it to come out of my system? Also i have been doing ovulation tests and have had positive ones and my periods have been regular straight after iud removal. Why now the sudden acne?!?!

Anyone please help!
