DH and I were suppose to try last night, which would have been CD 10. Last month I ovulated on CD 13 so that would give me a 3 day cut off. Well today I took my OPK and it looked positive, so now I think I may ovulate tomorrow CD 12. I got PG with my DS the night before ovulation after a long abstinence which is what we have had because I was sick, so I am thinking it is better not to risk it.
