My period isn't suppose to come on until tommorrow. But i don't think that it is. Usually i cramp the day before but i have been cramping for the past 3 days. Also i have been eating alot lately, mainly what i see my boyfriend have. And at times my nipples will be so sore that it makes my whole chest hurt. For the past 2 days i have had some bad headaches and so sleepy. Also my boyfriend called himself knowing what he's doing and we use da pull out method. Now i know this could be some effects due to stress but idk. Wat do you guys think.
