ttc 3rd month helppp

hey guys need a little advice. been trying to conceive 3 months now this month I've noticed a difference I have a 28 day cycle after ovulation tests were positive my breasts have been so sore since then&carried; on being sore feels like someone has got sand paper and rubbed them with it. I'm due af on Sunday but boobs are still so sore my cervix is high and soft but closed, I have wet creamy cm that hasn't stopped or dried up at all, have I got a strong chance and when is best to test I had niggly pain yesterday..
