High temp before period???

Hope

So I’m not sure if I’m pregnant or not but I’m wondering if anyone else has had this and ended up pregnant. I’ve been going from normal, to feeling overheated easily, to feeling freezing cold and then back to feeling normal and it’s a cycle of how my body decides to feel throughout the day. I’ve been having cramping - mild, lower back cramps (it’s not painful just annoying). I got a sharp pain near my left hip that lasted for a couple seconds and then went away. My chests been hurting, especially around the side and near/into my armpit area, I’ve woken up coughing, and a stuffy or runny nose but after I’m away for a while they both subside. I’ve also gotten random ear aches that last for a couple seconds to a couple minutes then go away - they aren’t constantly like a ear infection. I’ve also had weird dreams a couple nights that have made me wake up being confused and thinking wtf. And my temp has been elevated more than normal to the point that they’ve sent me home from work, had me get retested for the virus (it was negative). But my temps been between 99.1-100.0 for the past couple of days. I don’t feel sick just extremely tired constantly. I’ve taken two naps today and I still felt like my body’s tired. I plan on taking a test tomorrow morning as I’m due for my period. But my family thinks I should possibly go to urgent care to get checked out as only time I’ve gotten it below 99 is by taking a cool shower. I did have sex multiple times around the time the app says I was supposed to ovulate. My temp is usually between 96-97 and has never been this high before my period, nor have I ever felt like this before my period besides maybe cramping, nausea and then feeling extra tired as I’m also anemic, but I’ve been taking iron to help with my anemia especially around when I’m due for my period so it’s not as bad.
