Am I pregnant?

Natalie
Hello! Me and my love have been trying for a child for a year now. Lately.. I've been extremely nauseous, Sore boobs in the sense that anything on them hurts, mild cramps every few days, lower back aches and also headaches. My last period lasted only a day which is very odd and it was the 1st to the 2nd of March. Very light aswell. Am I crazy or is something going on? Advice please! Baby dust to all!!! 💘
