TTC2RM's Trying To Conceive Wish

I have a 15 month old, is it crazy to ttc another this soon??? Well call me Mrs. Crazy! I'm ready...maybe no one else in my life is but I am. I'm wishing on a star tonight (OV night). Been trying for 3 months so far nothing all the symptoms are there or could I be syking myself out??? I'll see in 2 weeks. God PLZ Bless me with #2!!
