Hard times and late night thoughts

I am having a really hard time lately. We have been TTC for 5 months now. I know that isn't much compared to some people but I had a chemical pregnancy the end of January. Getting that positive was so amazing and then it was just ripped away so quickly. Now, I have been having pain when we are having sex and I am honestly thinking I could have Endometriosis. I thought the pregnancy maybe failed because of stress from my job because a lot happened that month and I put in my notice because we want to start a family. Now I'm not sure what to do. Thinking of making an appointment with a doctor.
