Late Period

Heather

My husband and I have been TTC, this will be the 3rd month now. Ive been off birth control since July-ish. Well I’ve been tracking my ovulation and used PreSeed. I am now 4 days late and haven’t had any of my normal period symptoms. Took an early pregnancy test yesterday and it was negative. Today I started having some brown discharge, very minimal. Anyone else experienced this? Should I take another test? Maybe a different brand? Thanks in advance!
