am I sick or could it be?!

Er
So for about 4/5 days now I've had a queasy stomach..Saturday night at about 2 AM, so technically Sunday morning, I got so sick. I didn't throw up at all but I woke up with cold sweats, diarrhea, stomach paint and extreme nausea..I was gagging but couldn't throw up..I feel fine as far as that goes but I still feel queasy while still having an appetite. As well as I feel like I need to go to the bathroom but I can't. I've also felt really tired. I'm not sure if any of this is an early pregnancy section symptom or not. Another app I have is telling me to test today anyways so I think I'm going to. It also points out that some of my symptoms lately are signs. Anyone else have similar symptoms and get a bfp? Something also just feels off lately. Like I'm a little more moody or emotional and also at the same time out of it lol something just feels different. Pray for me that our time comes soon!
Side note: tues and Thur last week (so a couple days before my nausea started) my basal body temp was 98.8 and 98.9. I don't normally track it but felt like trying since my app told me to lol I'm gonna check it today also out of curiosity
