I am so confused

So I am officially 3 weeks late now and have negative home tests and a blood test of less than 2 even though I have been having the same “pregnancy” symptoms for four weeks now. My FSH and LH hormone levels were tested and they are normal. I have been using OPKs daily for the last two weeks and still am no where near a peak. My bbt has also been higher than normal for the past three weeks. It seems like AF is nowhere near as I have not been experiencing my normal PMS symptoms. I just want my body to gets it shit together so that I can actually start ttc again instead of being in a state of waiting. Has this ever happened to any of you?
