Im so scared! And dont know what to think...

So my husband and I have been TTC for 2 years now.. We had a miscarriage in April which was heart breaking.. I am now 21 days late with no signs of AF nor BFP. I used to get ovarian cyst but haven't in a while... It feels like its happening again but the pain and symptoms are so much worse! I am terrified to think it could be more then just a cyst! And its even more terrifying because I have history of ovarian cancer in my family! I'm only 23 and to think that I may have the chance of having my own family naturally! That is both mine and my husband's blood is sending my anxiety through the roof! I don't even know how to approach my doctor cause I don't know if my anxiety is just making me worry more and over think all of this! A lot of you are probs gonna judge me for this post but I can't speak to people about this I don't really have any one to speak to and I don't wanna worry my husband if all of his is in my head!
