I am not an expert so I'll just share what I experienced. For me, after the 3rd month scan was normal, my family and I felt we entered the safe zone and started telling relatives. Till then, we kept it private.
Honestly, for me, the real sigh of relief came after completing 12 weeks. Before that, I was so cautious. Once the 2nd trimester started, my energy came back and I felt much more relaxed. Just finished my delivery last month and baby is great!
Yes, the second trimester is usually called the safe zone. My gynac allowed me to start mild prenatal yoga and daily 30-minute walks only after I crossed 14 weeks. Always check with your doctor before starting any exercise though.
Most doctors at my hospital told me that crossing the 12-week mark (first trimester) is generally considered the 'safe zone' because miscarriage risks drop a lot. The hospital staff even gave me a detailed milestone booklet about it. Definitely ask your doctor for your specific case!
For me, the safe zone started at week 13 because my morning sickness finally ended and my food cravings kicked in! I could finally eat without vomiting. It's the best phase to enjoy delicious meals!
According to research and what my doctor explained, the risk of miscarriage drops to under 1-2% after week 12. Also, crossing 28 weeks is another milestone called fetal viability. So the first big milestone is definitely completing your first trimester.
Usually, once you cross 12 weeks, the critical phase is over and you can breathe easy. Even though I had some complications later and delivered via C-section, that middle phase of pregnancy was very smooth and comfortable.
