I'm 28!ttc since last summer

Kendra • Trying to conceive baby #2 since September 2015!
Been off bc pills for a year. .. still no baby. Tracking mucus and taking ovulation test... I'm getting positives and I feel like I'm doing all I can but still haven't conceived. I have an 8 year old. ...so if I'm not pregnant by 30 ima stop trying. Some people can't even have one. I think I'll be ok if baby#2 never comes to be.
