I have been ttc for awhile now with no luck....

So i start my period two days early and without symptoms... Usually my breasts hurt the week before and the week during my period. Well this time they haven't and i haven't cramped at all... I just feel this weird pressure and sometimes through the day i get sharp pains and I'm bloated.... Just wondering is anyone has and information. Also im ALWAYS a heavy bleeder and this time i can wear a pad and not worry... Help
