(Will choose best answer)Just got my MaybeMom saliva ovulation tester...Any ideas on best way to conceive?

Best answer will be awarded. I need your help now, we will be TTC in november, dec, jan and whatever time we have left in feb before my husband deploys, now the goal is to get pregnant before Feb 2010, only because his deployment is only 6 months long and that will put me being due after he gets home, and he missed our daughters first birth cause the military screwed us, and we would really like for him to be home for the next. So given this, I have 4 months starting in Nov. to get pregnant and not miscarry this time(just miscarried a week and a few days ago), I am already taking prenatal vitamins everyday(the doc recommended it and then prescribed them), and I have my ovulation tester to tell me exactly when I am ovulating, now I need YOUR help to give me any possible tips, hints, and ideas, to make a conception before he deploys in Feb possible!!! One problem, my husband MAY have low sperm motility rate, so I really need these tips. This is a very big deal to us, and this is the perfect time we want to conceive. Our daughter will be 3 years old(birthday in Nov.) shortly after this one is born next year(if we conceive) before he deploys, and we wanted our kids 3 years apart. So I need YOUR help(once again) to make this other little miracle happen. Please give ANY advice, tips and hints you have found to be a help in conception, especially in our case with a possible low sperm motility rate! Thanks so much, and I am awaiting to choose best answer! Please Help us!
