I haven’t had my period since November( I’m very irregular) and the last time I took a test January 3rd and it was negative, I’ve had a lot of sex since then and we don’t use birth control or condoms ( kinda in the mid set of were not trying but were not not trying). The past 3 days I’ve felt weird in a way that I’ve never felt before like I’m extremely tired with little bursts of energy,nauseas , huge headaches,cramps in my low abdomen, short temper with my dogs, emotional, gassy, constipated, and both huge and no appetite
