Frustrated

Hello Ladies,
​I am turning to you all because you are all in my mindset and position, everyone is driving me crazy! 
​My husband and I have been ttc for 6 months now and my period arrived yesterday. Each month we try and I think I might be feeling symptoms and the aunt flow comes for a visit. My friends don't have kids and aren't trying, they tell me I'm taking this all too seriously because I had stopped drinking and had been charting my bbt each morning. My mother just keeps telling me "relax, it'll happen" which ultimately throws me over the edge. I just don't know where to turn or what to do anymore.
