I’m not sure if I pregnant but last month my period was 12 days late then I got it, it lasted 3 days had a ultrasound and blood work done last week all negative but this week my nipples are so sore they gotten darker and around my nipples have gotten bigger, sometimes I’m very nauseous and other times I can’t stop eating and then a wave of me being nauseous again arrives. I’m super tired as well I don’t have much energy and I randomly got a cold I didn’t even feel coming on. If I’m pregnant I’m 2 weeks at the most.
