Increased appetite??

Faye • Currently taking 3mg Bromocriptine for high prolactin levels, 1000mg metformin a day for PCOS. 1 ectopic pregnancy ❤️
So I am 1 day late AF and postponing taking a HPT until absolute necessary to save disappointment and money ! (I have spent so much on HPTs it is ridiculous ! 
But this whole 'increased appetite' as a symptom I keep on seeing. Is it like eating more of your usual portions, or just complete and utter controllable munchies ?? I have been eating so much these passed 3 days I am making myself I'll :///
