TWW - How do you tend to approach it?

Do you tend to stay positive all throughout until AF comes, or do you try to manage expectations so you aren’t extremely disappointed if she arrives. I am somewhere around 8-11 dpo (different apps saying different things) and feeling different this month. I normally don’t have sore breasts, but I can’t barely touch them by accident, even on the sides. I also have a lot of indigestion which I never get. It’s still very early so it doesn’t make sense to me as I know I shouldn’t be having symptoms this early and don’t want to be symptom spotting and getting my hopes up. Had a MC in May 2017 and nothing since.

Any advice other than taking a test? I live in South Africa and don’t have those cheap tests to just test randomly. AF is due (and not welcome) on the 12th, so I will probably test on 13th.
