🎂
When were you born?
Age shapes your cycle in real ways — cycle length, hormone levels, fertility window timing. This helps us calibrate everything for you.
Did you know?
"Your cycle naturally changes across your 20s, 30s, and 40s. Understanding your age helps Bloom give you accurate, life-stage guidance."
📅
When did your last period start?
Day 1 is the first day of real bleeding — not spotting. This anchors all your predictions.
🔄
How long is your cycle?
Count from Day 1 of one period to Day 1 of the next. Most cycles are 21–35 days. 28 is a great starting point.
days
Bloom learns
"The more cycles you log, the smarter your predictions get. This is just your starting point."
🩸
How long does your period last?
Include all days of bleeding, even light flow. 3–7 days is typical — whatever yours is, is normal.

Good to know
"Egg-white discharge is the clearest sign of your fertile window. Your body has been giving you this signal all along."

Does your cycle affect your sleep?
Progesterone affects sleep quality. Understanding your patterns helps Bloom give you real, useful guidance.

What doctors say
👩⚕️
Dr. Sarah Chen, MD
OB/GYN — Johns Hopkins, 14 years experience
★★★★★
"Bloom is one of the few period tracking apps I actually recommend to my patients. The science behind the predictions is sound, and the cycle education content is genuinely accurate. I've seen it help women articulate their symptoms in ways that make my job easier and their care better."
✓ Recommended to patients
👩🔬
Dr. Priya Sharma, PhD
Reproductive Endocrinologist — Stanford Medicine
★★★★★
"The hormonal education within Bloom is unusually accurate for a consumer app. I've referred multiple patients — especially those with PCOS and irregular cycles — who report that understanding their cycle phases has meaningfully reduced their health anxiety."
✓ Recommended for PCOS & hormonal health
🧑⚕️
Dr. Maria González, MD
Women's Health Specialist — Mayo Clinic
★★★★★
"When a patient mentions Bloom in a consultation, I know they come prepared. The cycle reports they can generate are actually useful in clinical settings. I've been suggesting it to colleagues as an example of femtech done right."
✓ Used in clinical consultations
