Anxious

Hi there so I have pcos and I've been seeing a new gyn since January of this year 2016. I was taking birth control and he took me off in January. I have been having normal periods since February and the last time my period came was June 3rd and now it's July 18th and I still haven't had my period.  I have been taking my metformin when I remember and my prenatal vitamins. So far I have taken 2 pregnancy test and they were both negative. I don't know what to do. I don't have any of the pregnancy symptoms I've been reading about. Has anyone gone through the same thing? If so please help me 😩😩😩😩😩
