Coming off Dianette to TTC

Does anyone have any experience with coming off Dianette to TTC? (First time)
I've been taking it for around 2.5yrs and came off at the end of my pack last month and as usual had my withdrawel bleed. My partner and I have been having unprotected sex since.
 I'm aware that it can take a good few months for my cycles to regulate again, so I'm not really sure when I am due on...based on what I used to be like before the pill and when on the pill as it wasn't much different, i would've been due for AF yesterday/today. 
However...for the last 2 weeks ish I've had nausea and on/off cramps and unfortunately the delightful mood swings have returned, yet now, there is no sign of AF at all and I suddenly have EWM...so am I actually now ovulating and the last 2 weeks have been just adapting to not being on the pill? 
Any ideas would be great! Thank you 🙂
