Im 31 Years Old..Off The Pill After 14 Years Beginning

Im 31 years old..Off the pill after 14 years beginning of october and had 1 normal period last month but it happened on day 32..instead of a 28 day cycle. this month missed my period. Going on day 7. Feels like I am going to get it every now and then stomach feels upset and familiar menstrual like cramps..but nothing .breasts have been incredibly sore and heavy, nipples almost always hard... my breasts ache a bit day 1 and 2 on my period but never like this and never this long. Been on and off dizzy and tired most days. I have a discharge almost everyday and it's either creamy white lotion-like or clear...no smell or infection. I tested negative on a test on day 2 of missed period. Could I be pregnant. We were ttc alot before my period was due...
