Question for those who got a bfp

Cindy • My DH and I have 1 child together and have 4 all together. I have 3 from a previous marriage. We are currently trying for our last baby. We've been married since 05/14/16 and together since 02/10
I'm 6 dpo and I have been having period like cramps all day. All on the right side, (ovulated on that side this month), and my back has been hurting as well. Anyone else get this in their tww?
