So me and my boyfriend had sex 12/24/16 and my cycle down 5 days early 12/26/16 and wented up 12/30/16 . My cycle was suppose to come down 12/31/16.. while I was on my cycle I was having pains that i had before on my cycle , bad cramps, feeling weak , my breast got soft & my nipple spreaded , throat hurts . When I got off it I still feel the same way but 01/2/17 I started spotting.. I feel so sick , runny nose and bad headaches.. does this mean I'm pregnant or could it mean something else ?
