TTC after a reversal

Clare

I had a sterilisation reversal a few months ago. We have been actively ttc by tracking ovulation etc still waiting for my bfp. Currently 6/7 dpo and have the worst backache and cramps but no other symptoms. Has anyone else had this around this time and gotten a bfp? Or any other symptoms I can look for? is it just in my head that this could be the month!
