WeekTracker
Current week, days into it, and trimester.
Since conception date is rarely known precisely, medical convention counts pregnancy weeks starting from the first day of the last menstrual period — meaning you're already considered about 2 weeks pregnant before conception typically occurs.
The first trimester runs through week 13, the second through week 27, and the third continues to birth around week 40 — each trimester marks a different phase of fetal development and typical maternal symptoms.
