just a random question , if I was able to tell on a hpt that I was pregnant at 4 weeks... is that a good sign that my hcg levels are high? in wondering because since my 1st pregnancy ended in a miscarriage the dr had me draw blood last week and then today to make sure they were doubling at the right pace and they'd let me know the results tomorrow. thanks mamas 😁
