Normally around the 15th of every month but last time it had started.around the 22ND and ended by the 26 and it at first just spotting which I normally don't get then just got slightly heavier which was odd because I'm very heavy on my period
You might be pregnant but that's a lot of symptoms to have for only being 4days pregnant! There's no reason why being only 4days pregnant would make you out of breath, and your hormone levels just wouldn't be high enough to give you Morning sickness, forgetfulness and cravings. Also, most tests won't pick up only 4days worth of pregnancy hormones; you'll need to wait until after a missed period, as 2ndtimelucky said.
