symptoms before a missed period

I am 12dpo my period is due on Monday I normally have very sore and swollen breasts a week to two weeks before my period. But this time I have no breast pain or tenderness. I did ovulate this month as I used a clear blue advanced ovulation monitor on the 2nd and 3rd of April I had peak ovulation and we did bed on ovulation day but that's it so didn't really bed a lot this month as we have been very busy. 
I have had a lot of indigestion and have been very hungry. 
Could this be the month.
