TTC Issues

I’ve never posted on her before but I was wondering if anyone on here has had some of the issues I am having. I currently haven’t had a period since the end of June. I know that they say stress is a contributing factor but I wasn’t sure how true it was. My job has been so stressful and has caused me to start new medications. I only mention it because I am not sure if it’s the medicine or the stress. I really don’t know what to do at this point. I am going to the doctor on Friday to hopefully get some answers. Does anyone have any advice?
