The first day of my last period was Jan 1st, the lengths of my cycle are irregular. I try to keep up wwith my ovulation the best I can on the "flo" app. My breasts have been tender for 2 weeks now and my nipples just started to get tinder. I have mild cramping randomly and I stay tired. I currently take 10mg of Adderall 2x a day and I'm just wondering if that can give a false negative and when should I test, I'm weaning myself off of my adderall, I only take it if I need to do something important that day.
