feeling the pressure

Jennifer
Hi all, I'm TTC baby number 1 and have been for just over a year now. Currently 6 days late. I tested after 4 days late and it was negative. I've been having some cramping here and there, horrible headache last night and boobs feeling huge. Was planning to test again tonight or tomorrow morning but just had some light brown discharge... starting to worry that this might be my period starting? Have been really positive up until now that this is my month but now I'm worried to test incase I don't like the outcome. Feeling the pressure!
