This is my first O test ever. I had a hormonal headache/nausea 2 days ago, very sore breasts since yesterday, extra egg white CM yesterday afternoon followed by watery late last night. My cervix is SHOW. I felt pricking for an hour last night in my right ovary and out of curiosity took an O test today at 10 AM. Will an O test be positive during or after O, or just before?
