Trying not to lose hope BFN

I had a natural miscarriage on march 28th, only lasted for 4/5 days, its been a month already and since i stopped bleeding my husband and I have been TTC. Ever since. AF was suppose to be due today but nothing yet I took a hpt but it was a BFN. I broke down crying because I want to have a baby so bad. I haven’t had any symptoms at all besides some cramping here and there and some nausea but thats all. I dont want to count myself out just yet, maybe my cycle is not due yet and the app may be wrong!
