Elizabeth
Me and my husband have been married for a year, we have been trying to get pregnant for 6 months now.. and nothing.. we have figured out when I ovulate, he quit smoking, and I quit drinking caffeine... we are just having a really hard time with it... especially when we see all of our friends and family becoming pregnant.. we just can't help but think is something wrong? What are we doing wrong? And it's taking such a hard troll on our marriage... please help and give me some advice... what did some of y'all ladies do??
