Infertility doctor appointment.

Meranda • 1/5/13💜 7/12/17💜
Next month we have our first actual appointment with our doctor About not being able to get pregnant. Back in April I went but they told us to keep trying. I am super scared and nervous. I have one daughter but she has a different dad than my husband. I am worried it might be him. But I am very worried it's me. Ever since I have had her I have had cycles between 33 and 50 days. It's some what more consistent now. But my sister just found out she has endrometerosis so bad she has to has hysterectomy. I am worried i have it due it all my issues. Like this month my period is 5 days late and I have been having god awful cramps like almost in tears. I'm just so terrified of something being awfully wrong and I won't be able to give my husband a baby. Any advise or thoughts or comments about what to expect or if they had similar issues
