Please help. I have been taking tests but having to go by the ovulation date of this app as I don’t track ovulation. I am due on my period tomorrow according to the app (they are also very sporadic because I am breastfeeding).

I see a line and it seems to be getting darker but this would be my third pregnancy and It has never taken this long to get really dark. Should it not be very dark by 13DPO. Does this mean I am pregnant, having a chemical etc. i also have nausea, back pain, vomited today due to food and fatigue.

Yesterday and today I wiped and there was a little bit of brownish discharge. I never had this before.

UPDATE ☺️☺️☺️

I got my BFP 14DPO
