I stopped taking cerazette on October 15th but I haven't had a period. I know it can take a while, which I am not used to as with microgynon when TTC DS, I had to wait only 4 days for my period.
I was planning on coming off it at Christmas with a view to allowing my body to find it's cycle before TTC DC2 around March time.
In all honesty, I was glad to come off it after just five months- bloating, no periods but period pains every four to five days, spotty skin, mood changes, thinning hair, increased appetite, weight gain etc, etc.
So it has been about 5 weeks since my last pill. I had five days of very, very light brown smudge that looked more like dirty mucus (sorry!) a week later but that is it. My boobs were tender on and off for three weeks and I had period type pains on and off for the same length of time. I took a pregnancy test after 10 days and it was negative. Since then, nothing; absolutely nothing. No symptoms of anything! The good thing is my appetite has descreased, I am no longer bloated, my hair has stopped falling out, my skin isn't as spotty and I am more pleasant to be around. 
I think I just need reassurance that my period won't be long so I can start tracking my cycle. I am 34 if this may in any way help!
