Test or not to test. That is the question 🤔

So, one app says my period was supposed to start 8/21, and Glow says 8/24. It's now 8/25 and NOTHING! I have been super bloated, super nauseous 24/7, and I'm so tired. I think my boobs have gotten bigger, but not 100% sure on that. They do feel a little heavier. I want to test, but I had a miscarriage in February and have had BFNs ever since; so I guess you can say I don't want to be disappointed again. What do you ladies think? Should I test today?
