A colon polyp is a small clump of cells that forms on the lining of the colon. Most colon polyps are harmless. But over time, some colon polyps can develop into colon cancer, which is often fatal when found in its later stages. Anyone can develop colon polyps. You're at higher risk if you're 50 or older, are overweight or a smoker, or have a personal or family history of colon polyps or colon cancer. Colon polyps often don't cause symptoms.
A pregnancy is divided into trimesters: 1  the first trimester is from week 1 to the end of week 12. 2  the second trimester is from week 13 to the end of week 26. 3  the third trimester is from week 27 to the end of the pregnancy.
Per me using math... Divide 40 weeks of gestation by 3 = 13.33 per trimester! Week 1 to 13.33 weeks is 1st Trimester. 13.34 weeks to 26.67 weeks is 2nd Trimester and 26.68 to 40.00 Weeks is 3rd Trimester.
