Help! New to this...

Hi, me and my husband have only recently started TTC. I stopped taking bc in August, had my normal AF 8/14 then my next one came 22/9 and now I'm still waiting for AF this month. However, I have mega sore breasts, kept me up last night as they were so painful. Have been cramping for about a week (feels like normal AF cramps), and been so tired (more than usual!). Too scared to test yet as don't want a BFN but no sign of AF. Any one else had this?
