Please can I ask some advice, I’m getting a little worried. I have been using opk since CD 12 as I have 33 day cycles. I tested positive using a digital clearblue on CD 18. I then tested negative on CD19 and so on. Then on CD22 and CD23 I tested positive using the Sainsbury’s strip opk tests. I obviously BD on all the days and after positive tests. I have been keeping all my strip tests and the lines are pretty damn strong (although I think still negative) and I stopped testing at CD26. I have been having cramping since the original positive result and again today. Can I share some photos with you? I need some help
