Is this all in my head *UPDATE*

So I made a post awhile back and I wanted to give you guys an update. So I tested again this morning and it came back negative. I was going to go to the doctors on Tuesday but had to cancel my appointment because my client sent me to the store to go grocery shopping. I just don’t know what to do anymore. Should I wait until the day before I start my period or should I test if I miss my period? In the last post I made I took 4 tests and they came back positive and then tested on Sunday and it was negative. I tested on Monday and it was negative. Flash forward to this morning and the same thing happened. Both of my apps say that I’m 3 weeks and 1 day. At this point I’m very discouraged to keep trying. Let me know what you guys think.
