About a week ago, my breasts became tender. The pain has definitely improved a lot, then i couldn't even lie on my stomach.. but its still here ! :( I have tenderness and an increase in fatty lumps/tissue. i dont have specific lump, but more rolly fatty lumps or tissue. my breasts are tender to touch, (my left is a little bit more tender than to other)or press on and my nipples are very sensitive.. not sore just sensitive. Im on the pill and due my last one in 2 days so basically going to get my period this week. I switched pill brands this month but they were both combination pills so i dont know if this would be the cause. Im so convinced i have breast cancer since this started 2 weeks before im due my period which seems like too long for menstruation symptoms to start ? i also have a pain in a little area in my armpit.. which i think is a spot under the skin as im able to pick up my skin and it feels spongey. again i have no lumps at all. no redness or changes to nipples or size of my breasts.. and the fact the pain is in both breasts could it be cancer ? My anxieties are eating me alive :(

Bet all this stress will delay my period then ill be worried its pregnancy !! Please any help or advice would mean so so much :(
