Cerazette issues

[Hannahnana]

I was on cerazette for about a year and a half and came off it for about 6 months because I'm a bit weird and decided I didn't want to be taking tablets and blah blah but anyway! On the first day of my last period which was 32 days ago I started cerazette again, took it for 2 days as I have another medical condition and I noticed that the pill was affecting it! So I took it for 2 days, came off it and a few days later my period ended! My period came back and worked like clockwork only a few weeks after I came of it for the six month period and as of today I am about 2-3 days late! Has the cerazette stopped me ovulating this month even though I only took it for 2 days or is it looking like I have a bigger situation on the horizon. I am 20, not trying to conceive and I'm just a bit concerned!
