I am trying to conceive baby #4 with my fiance and he has no kids. We have sex everyday I have been using this <a href="https://play.google.com/store/apps/details?id=com.glow.android">glow app</a> since July! Do you think that he could have a problem? What can the problem be? We both decided to take multivitamins everyday! I am getting fed up! I am 29 and he is 26. Can somebody please comment or give opinions?
