Rant about TTC.... don't mean to offend

Why is it that couples who are trying to conceive (like me and my husband) can't seem to manage it with tracking and such...

While couples who do not want children at the moment (like a friend of mine and her boyfriend) manage to conceive in a singe night of passion with a bad decision to not use a condom.

Now she's trying to choose which option is best for her and what to do, and I'm trying to be supportive and helpful while on the inside I'm just so angry at the universe for giving the miracle of a child to someone who is not ready for it and doesn't want it right now.

Please don't turn this into a discussion for or against abortion/adoption.... I just needed somewhere to say this "outloud".
