Autumn

I been on the pill for over a year, the last two months ive been taking them on and off but more taking then not at all. Today I am 9 days late on my peorid and this month i been taking them but doubling every other day my boobs hurt and I've been spotting on and off could i be pregnant? I took a test thia morning it was negative but I been pregnant before and this is exactly how I felt.
