What the heck?🤷‍♀️

On November 18 I got what I thought was my positive opk⬇️

The next day when I tested again it was super negative and it has been since I stopped testing 3 days ago. Tonight (Nov 28) I tested again because I've been having weird cramps and more clear discharge than usual. I got this⬇️

Can anybody help me with this? Anyone experienced this? Whats going on? Did I miss my window? Hubby is out of town until this weekend and I'm afraid we won't be able to BD when we need to😩
