Trouble sleeping.

I<3Dolphins • I`m a 23 year old Military wife. My husband and I have been TTC #1 since November 13, 2013. ✨
I have 2 questions...
​I have trouble getting  to sleep at night. I usually always wake up anywhere from 10-12 depending on what time I finally fall asleep. Would my inconsistent sleep schedule make it harder to get pregnant?
​Because, I have trouble sleeping, I usually take ZZz quil before bed to help me get to sleep. Would taking that also make it harder to get pregnant?  
​If you have any suggestions on falling asleep faster, please let me know. 
​Thank you.
