I really want a child

Honestly... I want to have a baby...I about cry every time I see a mother and child out and about. I want that life, I am about that life. But it hard to know when you are ovulating...I have had periods this month that were two weeks apart. I had sex a few days ago when I saw that my cervical mucus looked like egg whites. It is so complicated because it's like I have sex once a month. But this time it was two days after my period ended. I am hoping this time is it.
