Trouble TTC number 2

How long did it take you ladies to conceive number two? My 5 year old was not planned and I was very young when I had her. After having her I have been on numerous bc pills and even had an iud at one point. My husband and I have been ttc since September and I have been off bc since August. I'm just wondering if it's taken anyone a long time to conceive again or if anyone's had fertility problems arise after already having one child. My husband and I are young, early 20s. We're healthy and already have our beautiful 5 year old daughter and I'm just starting to get my hopes up. :/
