Common Questions
Is the due date perfectly accurate?
Only 5% of babies are born on the exact date. Most are born between 38 and 42 weeks of pregnancy.
How does it relate to ovulation?
Conception happens during ovulation, but pregnancy is counted from the start of the menstrual period because it is an easier date to remember.
What is pregnancy tracking?
It is keeping a calendar or diary of your symptoms month by month. With Bloom, everything is kept private.
