Periods

Jemma
Hi I was on the pill for 6 months then had a months break and went on the patch. Was on that for 2 months b4 coming off to try for a baby. 1st 2 months my cycle was 30days. Then I had 2 periods in 3rd month. 4th month was 30days and last 2 was 25 days. I'm expecting my next cycle in 4 days time. Iv been on pull and depo b4 and never experienced this. Has anyone else as I'm stressing as we really want a baby and I don't know if my body is just buggered and I won't be able to conceive xX
