Norethisterone affect ovulation?

We got married in October and jetted off on our two week honeymoon. I was due my period 5 days into my honeymoon so took noresthisterone to delay my period. 
My period arrived when we got back 4th November and lasted like it normally does 5/6 days. 
So this is now my ovulation week according to the 14 day rule. I'm taking ovulation tests, I have been since Friday but I'm not getting any positives. I actually feel like I am going to come on my period, I'm bloated, have a headache and am a bit moody. My normal period date is around 20th - 22nd of each month so these symptoms would fit with me getting my period but because of that pill I thought (and have read online) that my period date is now different. 
This is our first month TTC so I can't complain but it's just frustrating not knowing my cycle and feeling helpless not being able to do anything about it. 
Anyone had any previous experience with this pill, does it mess up your cycle / ovulation dates? 
Anyone taken it and fallen pregnant straight after?
