Going crazy

Here is my story, my SO and I decided to get off the pill in March, by June I still hadn't had a visit from AF and neg tests, went to the Dr and had test done, not pregnant and everything was normal so she gave me meds to take for 5 days to start my cycle. Got my AF 3 days after taking the meds, that was july 13. Fast forward to today, I am 2 weeks late, tested when I was 3 days late and had a very faint line, posted on here to make sure I wasn't seeing things. We decided to get a digital test and wait until I was 2 weeks late and use it, well this morning when I took it it said not pregnant. I have been having lots of symptoms, some just started this last week, even had super thick discharge, no odor nor color early this week. I have no clue what to think. Maybe I ovulated later who knows, I just hope I don't have another almost 4 months with no AF and not be pregnant.
