NWR...a little worried...kinda long ***UPDATED**

Here is a little history...my period has never been regular. there was even a time where i missed it for 7months. my doctor had me take a few tests, found absolutely nothing and gave me pills to jumpstart my period. and he said i would continue to take these pills untilit was time for me to have kids. Luckily I didn;t need to take the pills(except for the 1st time) my period started to come on its own......until now. I have already missed 2 periods, going on my third. I have taken 2 home pregnancy test, both came out negative. i have an appointment with my dr today at 6. i'm just afraid of what he might find. if i have to take these pills again, tha means i'm not ovulating properly, which means i'm going to have difficulty getting pregnant when the time comes for it. i'm just a little stresses. i needed to get that off my chest. thanks for listening.


**UPDATE**
i got back from the doctor. he said everything is fine. he gave me the same pills as last time (to jumptart my period).
