Hello. I am pretty new to opks and just got my IUD removed last month, so unsure of my cylce. I was testing with equate brand which are a rip off in my opinion. I was barely getting color in both the test and control area. I bought some dollar store opks and did this one today. Did I miss my surge or possibly still to come? I have sore breasts, and slight cramps that could be o? I know this is negative but do you think I missed my o or it's still to come? DH and I BD yesterday, but he has been sick and had a coughing spell and didn't finish. Ugh, just bumming if I missed my window.
