Messed cycle - PLEASE COMMENT

So I have a cycle of 34 days. I had a period 8th June so I WAS due for a period the 12th July (2 days away.) I had a light bleed half way through my cycle so I pressed start period on the app and now I have some what I think may be pregnancy symptoms such as; sore boobs, right ovary ache, dizziness when getting up and have slept a lot this week. I took a test which had a second line but it was white? What should I do? Test again?
