Also forgot to mention I asked my RE several times if this was "normal" and she said it is very common.
Good luch to your :)
I got my BPF this month and I was sure that AF was on the way. I had exact same cramping even stronger. I also was spotting one evening but then it dissapeared.
Good Luck
I experienced AF type discomfort several days before AF was due and tested postitve on cycle day 31. I continued to feel like AF was coming for several weeks after.
