Tmi! Need opinions!

I'm 8dpo and af is due 8/22. Obviously super early to test but ive had slight cramps the past 2 days and my cm was very thin but sticky. And it was like in between cloudy and clear and there was quite a bit. Havent BD in 3 days. Been TTC for 9 months but have had some hormone issues. I've always had irregular periods but my ob gave me Provera and had a normal cycle after. And I've never really experienced PMS or even period symptoms before. So didn't know if this was PMS or if I should def test in the next few days? Need some advice. Sorry its so long. Not very many people I can get advice from so I thought I would try here.
