Help with pregnancy?

In april my period was 8 days late. It was supposed to start the 19th, but it came the 27th. It lasted til the 2nd. I tested and it was negative. My next period was supposed to be 14 days ago, i tested when i was 10 days late, and boom... pregnant. Since my period was 8 days late in april i dont know how far along i am or if it was a period.
