Could this be it....?

Ka
I'm on cd 24 about 7 dpo with 7 days until af. Usually I would be having lots of pms by now but nothing. My boobs feel bigger, but not sore and full like normally. I've had some light cramping, but also not as bad or as long lasting as usual. I've also had lots of nausea and headaches which is also very unusual. I'm too nervous to test this early, so does anyone have any advise. I really hope this is it....
