ttc after miscarriage

Hello ladies!! at age 19, I had my son who is now 5 years old. I was a single mom for 3 years. so I met my husband 2 years ago and he does not have any kids of his own. we tried since day one to get pregnant and nothing. December 2017 I found out I was pregnant. during Christmas I decided to tell my husband Infront of the family. Christmas morning I had a miscarriage.... since then I have been trying everything to get pregnant and nothing seems to work. any advice or any pills i should take please help. I'm desperate and sad that nothing helps. i know Gods planning is perfect. but I just need a lil boost
