CP I think...

Je
4 days ago I tested and had a vvvfl. It was 6 days till my period. Reason why I tested early was cause of how I was feeling. Never felt like it before with certain symptoms. 
Now this morning (2 days till AF ) I woke up and took a test and nothing was there... Three hours later AF came with a war behind her. Horrible cramps in my back and stomach, and so many blood clots. 
Because I did have that vvvfl, I am assuming this is a CP. which I am so sad. 
I never even knew a CP was until today when I started looking online. 
I feel crazy because I am sad....
