Cerazette - PMS Like Symptoms And Mood Side Effects

I am unable to take pills with estrogen in them (due to a family history of blood clotting), and so have tried taking Cerazette to help with my PMS and period symptoms. My PMS symptoms are the worst between around Day 18/19 when progesterone is highest, so I was reluctant to take a pill that would introduce even more progesterone (especially an artificial kind), but as it is meant to suppress ovulation (which would ultimately reduce that progesterone peak) I decided to try it out.

Anyway, I started taking it around Day 20 of my cycle. At first things were REALLY good. Like it seemed to stop my PMS almost instantly and I was feeling great. A little bit more hungry, a bit of light nausea and headaches, but mostly feeling really good - a lot better than I normally would at that time of the month. On Sunday (day 27) my period was due, but didn't arrive, so I was really happy, but then randomly started feeling a little bit down in the evening in a PMS-like kind of way. On monday, I was mostly fine all day but then got a really irritable over one little thing in the evening. On tuesday, I felt yukky - very much like my usual PMS - I was cranky, tired, hungry and got upset over the silliest thing - And then started bleeding, and felt a lot better once the bleeding started. By thursday, I was still feeling a bit moody, hungry and insecure, and got a large pimple (and I never get pimples!) so I decided to stop taking it and didn't take my pill that evening.

On Friday, I actually felt worse! Couldn't concentrate much at all and was feeling really stressed out that I'd never find a solution to my PMS etc.

I think I want to keep going on Cerazette because I have had some good experiences on it (i.e when I first started taking it), but I'm terrified about the potential mood side effects and am worried it'll make me bitchy/anxious etc.
