Anovulatory cycle after miscarriage

DOL

I had a miscarriage on 9th December. It took a while for my period to come back and then it was weirdly lighter and less painful than normal. I’ve been tracking my cycle and got my peak OPK yesterday. This morning it has faded quite a bit but no rise in BBT. I am at the end of my tether and I know my doctor won’t care. I’m in the UK and the NHS has a ‘wait and see if you have another two miscarriages’ policy so they’re very reluctant to discuss anything with me about my miscarriage. I feel like I’m bothering them. Has anyone experienced this?
