Confused! LH low

Hi all. I'm New to the forum but after some advice I've always had off periods, but I've not had one (or symptoms) at all since January. Me and my fiancé would like to try for a baby and I saw my Gp. She ran some blood tests and everything is fine but I have low LH Levels. I was prescribed notethisterone for a withdrawal bleed to try trick my body into re syncing. Have any women had this same issue and still conceived? I will be referred to obs and gynae but I'm feeling pretty frustrated with all this. I'm tracking as much I can from my withdrawal bleed but if I'm not ovulating what can be done? :( any help or advice is appreciated. XX
