Confused..mixed emotions and anxious

I

OK so beginning of Jan did a test it was positive, I did a digital one which showed 2-3 weeks. Now past 3 days I have been having brown/pink discharge/streaks which is like a light period. It did get darker like a maroon/red 2nd day and back to being dark brown. Every time I wipe down it's coloured the tissue. I have no cramps or abdominal pains. I went in to have a early scan. Sonographer wasn't very helpful and never showed me the screen or said much apart from sac like structure is there and that's all she said. They had to do abdominal scan and a transvaginal scan. I also had blood tests done and will be going back on wed tomorrow for another blood. I am just so worried as I didn't really have pregnancy symptoms to begin with apart from sore breasts but that has now faded and don't feel pregnant much now.

I'm praying it will be still positive despite this. Anyone else experienced or experiencing this or similar? By the way I did do another pregnancy test today as it's getting me om edge. It's showing pregnant now with 3+ sign.
