Hi girls! I was just using those ovulation calculators as well, when I got the ovulation predictor kit I realized I was actually ovulating early than the calculator said however I still take the entire week that it predicts I could be fertile and make sure we BD everyday, just in case. Here is a link for the abbreviations when I first signed up I had to check for almost every post

MPrim- I have used the OPKs but I haven't tried temping yet. I think next cycle I am going to do both, I liked the OPKs but then I kept thinking what if it was wrong?! I guess with both you'd have some confirmation that this day is def when you ovulated. Which then you can obsess that you'd 12dpo and you haven't gotten a positive yet, I'm pretty sure that's where I am at right now haha
