The OPK Lovemaking calculator lets you know when to make love after a positive OPK.

The Ovulation Predictor Kit (OPK) Ovulation Lovemaking Calculator tells you when to start making love by calculating when ovulation happens after a positive OPK.

Here are some facts about fertility and making love:

• Your chances getting pregnant are close to zero if you make love only after ovulation
• Your chances getting pregnant are diminished if you make love only once, even if it's the "perfect" day
• Your very best chance getting pregnant is when you make love regularly 2-3 times a week EVERY week
• Making love only during the fertile 5-6 days prior to and the day of ovulation improved your chances getting pregnant but is not as good as also making love outside your fertile days
• If his sperm count is OK then making love once a day on every fertile day is better than every other day or even less frequently
• You usually ovulate WITHIN (NOT AFTER) 12-34 hours after the OPK first turns positive. If you make love only after the OPK first becomes positive chances are you are less likely to get pregnant as compared to making love regularly
