My period ended before the 4th of October. It lasted for a week or so. As of now my nipples have suddenly become very tender and are sore/tender when i touch, massage or rub thrm against anything. I feel extremely tired, moody and hungry, my breasts feel heavy. Im constipated and i feel nauseous randomly but especially when i need to poop. Wondering if i should take a pregnancy test or if im being paranoid
