I am married for 7 months now but am not pregnant?

Probably no problem: It takes an average of 6 months to conceive a baby, meaning half of couples take longer than 6 months. There is no reason to be concerned unless you try for a year without getting pregnant. If this happens have your husband's sperm count checked and have yourself checked for hypothyroidism. If those are fine then see doctor for other tests. Taking a multivitamin and 5000 iu of Vitamin D may help.
