It is so hard to not test a little TMI

Omg I am just having such a hard time waiting this week out. Day 3 of no period but I am scared I might have an infection. Going to the doctor next week if it is a neg result something is truly wrong with me. My list consists of vaginal pain (honestly it might be a tear will be checking later on), Sharp pain on my sides, nausea to the max at night and in the morning, back pain so so bad, and last my breast are killing me oh and headaches that started yesterday, I don't even want to eat. But I don't want to test now cause I just got a BFN last Wednesday morning which was two days before my period. So I really really want to wait till Saturday for me to not go through the week sad. Feels like the longest week ever. How do I deal with this? Was going to take relaxing bath tonight and cuddle with my boyfriend. But I still have 6 days to go. At least I have a busy week working a lot and I have school. Any advice to stay calm?
