Very sad

Hey guys so I lost my baby April 4th started getting my period back May 7th and since then it's been pretty regular. It has been coming between 6-8. 31 day average. So I haven't gotten my period yet. And I've taken countless test and some are faint others are clear negatives and even yesterday the digital was negative. I feel like if I was pregnant it would show by now because with my last pregnancy the line were so dark on the day I was suppose to get my period. I'm so sad and terrified that my period is just changing dates and I'm not going to get the answer I truly want. Anybody with a period of September 6-8 get a bfp yet? I have a doctors appointment on the 29th and I'm having the exact same symptoms I had when I was pregnant with my last baby. I just want to be pregnant but I feel like it won't happen again😪😪😢😢🤧🤧😔😔
