Working out while trying to conceive

Will working out/lifting weights hurt my chances of conceiving? I just started hitting the gym pretty regularly with my husband less than a month ago. We go 3 days a week and I do squats with the bar and weight added to it on a smith machine, then I'll do shoulder press, rowing, chest press and cardio. Regarding cardio, I run/walk 5ks at least once a month. My husband thinks I'm crazy but I'm afraid the squatting with screw with possible implantation particularly. 
Any thoughts?
