ahhh yet another negative. advice please :(

so I ovulated early this month (using clear blue ovulation tests) glow jumped my period forward a bit when I put in I ovulated early saying I was due today. so I took a test and it's negative. but I've had sore boobs now for a week and a half. starting to think I'll only ever have one child and that's my lot. starting get down now 5 months of trying. I don't know how you girls do it for years and years. Don't know when period is due properly? Don't know when to test again? feeling fed up
