So nervous idk what to think or feel

So my SO and I have been trying for about a year or so since I had my 2 miscarriages. I am in my tww and I’m going insane. I was on fertility meds and I got my progesterone levels checked on day 21 and they were at 29 which is the highest I’ve ever had them before so I for sure ovulated. I’m 9dpo and been cramping like crazy from idk what. My period is due in 5 days and I’m just not sure how to feel. I want to test but I know it’s to early. What I’m trying to say is when is the best time to test? And has anyone else cramped while in their tww. I rarely ever cramp with my periods and I know it’s not period cramps bc this is a didn’t kind of cramping.
