To test tomorrow or wait?

According to my app I am 10dpo ( not sure due to not using opks which I don't use due to having very prevalent ewcm) today. I have had a couple moments here and gone nausea today. Yesterday while cleaning the house I got really light headed when normally I could go all day with no problems. Only my right boob is sore.

My cycles have been 25 days since my hysteroscopy with usually 4 days of brown spotting before which hasnt started and cd25 is Wednesday the 15th. I want to test tomorrow but also don't want to be disappointed with a negative result.
