So I had nausea for 2 days along with urinating often then yesterday I started my period with lower back cramps and lower abdomen cramps. I’m not expected to start my period for a whole 7 days . I have never started early ever. Today I am still currently having nausea, urinating frequently and tired . I’m sure it’s not implantation because I’ve never had that before and im bleeding like a period minus the crazy cramps I usually get these are deeper and way lower. Any insight ? Thanks ladies in advance.
