trying for my #2 & his #1

Hannah • Hey 👋🏽 guys. 2 year old. Engaged. Trying for baby 👶🏽 number 2! 😍💙👶🏽😘🙌🏽
Hey guys, my name is Hannah. I'm new to this app and after reading on the app and about it I'm really excited to use it. I'm 18 and have a 2 year old son. Me and his father are not together. On the other hand I am engaged getting married on September 2nd 2017. Me and my fiancé have been trying to get pregnant. We've been trying for almost 4 months now. We started after I got my BC out in August. Being a mother is what I'm destined to do. We had sex on the last day of my ovulation hoping it worked. I'm supposed to get my period on the 25-28th I'm praying I miss it. BUT on the off chance I don't what do you ladies recommend we do to help with trying to get pregnant. It'll be his first and I'm so blessed and excited to give him that beautiful baby. HELP! Literally loosing my mind.
