My husband and I miscarried a baby on September 23, 2011, this was my second pregnancy. We have been trying to get pregnant again ever since, we have sex often around the time of my ovulation but for the past 5 months nothing has happened. My ob doctor doesn't know what it is and doesn't care to find out so I'm currently searching for a new doctor but I was just wondering why it is that we can't conceive again or if there were any tips to help us.

I am sorry to hear of your miscarriage. It is important to keep in mind that while most couples will become pregnant within a year of trying, some take longer. For this reason, doctors generally will not be concerned if you are not pregnant yet. Looking for a possible cause usually will not happen until after a year of trying. I know it is frustrating for it not to be happening sooner, but it is not unusual that you are not yet pregnant again.

Timing is only part of the equation in becoming pregnant. How have you determined when you might be ovulating? Do you have sex at other times as well?

I've been tracking my periods and such with http://www.mymonthlycycles.com/ and I have been using ovulation tests. We try to have sex at least twice a week.

Have the ovulation tests worked well for you? The online calculators will give you a starting place, but also watch for changes that you might be able to notice. A very telling indication can be when cervical mucus becomes more clear and fluid. If you notice that this coincides with the timing of expected ovulation, start trying several days sooner and right through expected ovulation.

Pregnancy is most likely to occur if sperm are already present and waiting for the egg to be released. Having regular sex in the days just prior to suspected ovulation can cover your timing in most situations. Since some women will naturally ovulate outside of the norm, the calculators would not work well for them. Having sex about every other day, if feasible, throughout a cycle can usually cover the timing aspect.

Again, even with good timing there are other factors that play a role in conception, so any one of those being a bit off can inhibit success.

The key is frequent sex, unless a known sperm count issue is present, taking care of yourselves with healthy habits, and trying to not let sex become a chore with pregnancy being the ultimate goal.

I hope it doesn't take too much longer for you!

I will agree, it can take a healthy couple often a year or even more so I can see why your doctor may not be too concerned yet.

I have a good feeling that this month will be the month.
