Bbt help please

Amanda 👼🏼🌈👨‍👩‍👦

I have been taking my temperate for about a month now but since the 28th my temp has been between a 97.7-97.9 this morning when I took it it jumped to a 99.5. Normally it is under the 97.7 mark for the most part. I am a few days late on my period so I'm not sure if I should take a test or wait it out. What do you think? I need some help please!
