I am very nervous/anxious and think I might be pregnant. I am supposed to start AF in about 3 days. I have felt "weird" these past few weeks. I am very gassy, I have not felt nauseous until just tonight (have not gotten sick, just felt uncomfortable) I have had minor cramps or pressure which I have thought was from being so gassy. I have been a bit more tired than usual but not something that has grabbed my attention. Normally about a week before AF I get very tender breast and I have had no signs of this this time being so close to her arrival. I have been going to the bathroom very frequently but also I've been drinking lots of water and been very thirsty. My gums have been bleeding everyone time I brush my teeth. Should I wait to take a pregnancy test until after I am supposed to start my period?
