I was supposed to get my period yesterday but hasn’t come, I’ve been having symptoms of nausea, feeling hungry and sick at the same time and excess saliva. Not to mention HEAVY mood swings that’s been driving my partner crazy. I’ve been sleeping during the afternoon for hours but at night I can’t sleep at all. Also I’ve had back pains that hurt so bad like 24/7. Could I be pregnant? Is it worth taking a test?
