If you're 1 months pregnant, you are approximately in weeks 1–4. This puts you in the first trimester. Here's a brief overview of what to expect during your 1st month.

Quick answer

Weeks 1–4

1 months pregnant covers approximately these weeks. First trimester.

What happens during month 1

Pregnancy is barely detectable. The fertilised egg is implanting in the uterine lining.

How months and weeks align

Pregnancy is counted in 40 weeks (~9 months) — but those 40 weeks don't divide evenly into 9 calendar months. Each pregnancy 'month' covers about 4.345 weeks. So month 1 = weeks 1–4 approximately.
