That's the right answer.
Your growing baby is pushing on your bladder, making you need to pee more often. The increased need to pee may also be due to increased blood flow to your kidneys when you're pregnant. Although this symptom usually improves in the second trimester, it may become even more of a problem in your last months of pregnancy.
Other early signs you may be expecting? Swollen and tender breasts, nausea, fatigue, and sensitivity to smells are all indications that a baby is in your future.
