TTC Newbie!

Emily
Hey guys! I'm new to this but have a TON of questions! 
I'm TTC baby #1 for about 5 months now. I got my IUD removed in July. (Had it for 5 years)
AF Is regular comes exactly when she is expected 😤
Does anyone have any tips for me to really get this show on the road? My bf & I really want to have a baby soon. 
Anyone think that my IUD made it harder for me to TTC? 
ALSO, I'm nervous on how to tell my OBGYN that I'm TTC. Should I wait a couple more months? 
Thanks loves! 
& good luck to everyone!
