My husband and I have been trying to get pregnant since January of 2010 with out luck. I have a child from a previous marriage but my husband does not have any kids. I went to see my obgyn about this and his advice was for us to only have sex on days 12 to 16 counting up from the first day of my period. He then said if that did not work I may need to go have an HSG test to see if my tubes are blocked from having my son by C- section.Is there any other advice that you can give us that my Dr did not?
