Ok period started a day early light bleeding for two days then spotting barely for three my question is could I be pregnant it was four weeks when my period started from last start id be in week 6 right now in the evening im getting neasea and cramps that upset my stomach they dont hurt but make me feel like I need to throw up my boobs do not hurt and are not big like before period tmi I guess trying to cover everything should I take a pg test?
