The past few days i've been really sick. i've had cramps and been throwing up alot!  i took 3 pregnancy tests after realizing it might be that...1 positive 2 negative.  i've been pregnant 4 times before but i never get sick i usually just miss my period and i haven't got my period in..a little while. i haven't been paying attention to it cause i have a lot of stress from my divorce...i also gained a few pounds but thats cause i'm eating a lot and i think thats cause i'm depressed, ugh this sucks, my pregnancies are always a missed period and the pregnancy tests i take all usually come out positive...should i make a doctors appointment or am i over reacting?
