Here is Deanna's plan. I have no idea if it would technically sway boy or not, I am only going by people who were NOT swaying and used this plan. They all had girls.
The Plan
Short Version:
"Try" every other night starting Day 8
Buy 10 ovulation predictor kit sticks
Begin ovulation testing on Day 10
When test is positive, "try" that night, plus two additional nights in a row
Skip one night, then do one last "try"
Take a home pregnancy test 15 days after your ovulation test was positive, if your period has not begun
If your ovulation test never goes positive, continue "trying" every other night until Day 35, then do a pregnancy test if your period has not begun.
Statistics coming in from women who write me show that about 40% of post-miscarriage women will get pregnant on the first try if they are faithful to the plan, about double the number of the normal population who are not on the plan. This assumes, of course, that you waited for a normal cycle to begin after your loss, and did not begin trying before having a period after a miscarriage. Many women do not ovulate in that first cycle.
Detailed Version:
On day 8 of your cycle, counting from the first day you bled, begin "trying" every other night. Begin taking Ovulation Predictor Kits (or continue with your Ovulation computer) on Day 10. Buy two five-packs so as not to scrimp on taking them and stop too early. To make sure your OPK is working well, take your test in the afternoon or after work and do not drink any liquids or go to the bathroom for at least four hours prior to testing. (Morning is not a good time for OPKs, which look for the LH surge, which usually happens during the day.) Read your OPK instructions carefully, as usually a faint line does not indicate a positive, you need a line that is darker than the test line. LH is produced throughout your cycle and will only predict ovulation when it has a big surge.
When your OPK turns positive, begin trying every night for three consecutive nights, skip the fourth night, and then once more. Then stop! The waiting begins.
Take a home pregnancy test 15 or 16 days after your OPK was positive if your period has not begun. Do not buy internet pregnancy tests or tests that claim to work before your period is expected. They are not well manufactured and are not reliable. They will only cause you more anxiety than you already feel in wanting to know. Please resist the urge to do a blood test at your doctor's office just to find out sooner unless you have a medical reason to know early. Fertilized eggs that do not grow are actually a terrible but normal occurrence as much as 75% of the time, and seeing a very low put positive blood test in the first 14 days can place you on a terrible emotional roller coaster. By the time a home pregnancy test is positive, your baby has safely implanted and your odds of miscarriage are down to a normal 10%.
Should your OPK never become positive, keep the every other day trying going until day 35. I recommend at that point taking a home pregnancy test, but even if it is negative, you might want to take a quantitative hCG blood test at your doctor's office. Remember that not every women will ovulate every month. I personally did not ovulate for two months following my first miscarriage.
As you are trying, make sure to "release" the sperm in your partner at least once during the gap between ovulation and new cycle Day 8 so that no more than 10 days elapse without new sperm production. Sperm is also a cause of genetic damage, not just eggs, so keep it fresh! If you are not successful the first month, it is not because your sperm did not get to your egg. 75% of eggs are lost within the first 14 days due to normal genetic damage or failure to fertilize. Just keep trying!
