Frequently asked questions
Why am I suddenly hungrier?
Energy needs rise in T2. Aim for ~300 extra cal/day — dal, eggs, paneer, nuts, fruit.
My libido is back?
Yes — the “golden trimester” brings more energy. Sex is safe in low-risk pregnancies.
Mild round-ligament pain — serious?
Short sharp pulls as the uterus grows are usually benign. Severe or sustained pain needs review.
For partners
Plan a small T2 “babymoon” — even a weekend getaway counts.
Prepare for your OB visit
- Can I start prenatal yoga / swimming?
- Any GDM risk factors to screen early?
