Cramps after eating!

ttc for rainbow baby • My husband and I have been together 7 years. Married since Aug 2014. We started ttc in July 15 and got pregnant first month and it ended in an ectopic. We are now waiting for our rainbow baby .
I am 12 dpo todsy and I have been getting cramps everytime I eat. Is this normal would that be considered nausea? I am still getting bfn. I really hope.i get my bfp!!
