I dont even know anymore..

My boyfriend and i have been trying to concieve for about 7 months now.. It has been crazy honestly. Trying to track when I ovulate with irregular periods is very stressful! My bf doesnt understand all the things you need to do to concieve. eat well, vitamins, tracking ovulation... etc. He thinks it will just happen. he eats so unhealthy and always eating with him turns me to those foods also. we have just been bickering a lot lately.. over the littlest things! its ridiculous! Im scared one little fight will turn to something big! Im just ready to get pregnant already!!! lol He is ready also. does anyone know any tips on TTC or advice on my bf.
