Second trimester of pregnancy – weeks 14-28

Learn about what to expect during your second trimester of pregnancy.

The second trimester includes from 14 to 28 weeks of pregnancy.

It is a time when early symptoms subside, your body grows and changes and you often feel the most mobile and well. You will have a 20-week anatomy scan, a diabetes test at around 26 weeks and Rhesus negative women will receive Rh(D) immunoglobulin (‘anti-D’).

Common challenges include changes in your sleeping patterns, positions, the development of reflux, increased pelvic and back pain. A minority of women will develop early pre-eclampsia, early rupture of the amniotic membranes or preterm labour.
