Help Please!

My hubby and I have been ttc for 5 months now. With our first child it happened the very first month we tried and this time it just isn’t happening. For some reason when I ovulate I have cramps and bleed slightly, but my CM is not watery/egg white like it used to be when we tried for our first child. There’s barely any. I’m beginning to feel really discouraged and I’m not sure what to do. Any advice?
