Help!!

I’ve been on birth control for 4 months, 2 months ago I had a pregnancy scare, and had a normal period and took a test just in case, it was negative, but this month I took another one just to be safe and it was negative again, and I’m on my period but had drown discharge before my period.. I’m just worried because they were blue dye tests and now I’m worried I should’ve taken a pink dye one... Help :( my anxiety is sooo bad
