BFP at 10DPO!!!!

Fiancé and I thought we were out this cycle especially since I tested at 8DPO and it was negative! Well, 2 days later and we got our BFP!!! Used Easy@home pregnancy strips and saw visible faint lines. Used a dollar tree test and saw a faint line. Confirmed with first response 6 days sooner digital testing and got YES+. Expected period is in 3 days. Symptoms before missed period: constipation, fatigue (literally fell asleep for a split second while listening to hubby speak), almost threw up due to a scent, sore breasts, dark urine (it's usually clear), headach even after being hydrated

and telltale sign...minor cold (runny nose and sneezing... that never happens to me before period).
