I haven't had my cycle yet since June 18-22 my last cycle I had

I took home test it was negative because I missed my cycle last month in July and the other day I went to dr to do my female check up and took their test it was negative also now I have to wait In 2 weeks to go back to my female dr and talk about my results and talk a blood test and see what's going on with me and do alter-sound to see inside of me and see also. I took birth control pills for 9 months and I quick taking them they was making me gain weight really bad and I had more painful symptoms after my last cycle I had in June after that that's when i was getting these symptoms now week I have to take few home pregnancy test that's what my dr told me to do.
