Karageorgou on "Headache?"

Hi - I'm in my 2ww of third fresh IVF. My beta is this Friday (9/12). I typically end up getting a headache a few days before AF arrives (presumably when progesterone starts declining) during my BFN cycles. I got one on Saturday (5dp3dt) and still have it today. This is a little early for my AF headache. Do others get these headaches and still end up with a BFP?

Thanks!
