At 10 weeks my pregnancy symptoms disappeared

Your typical pregnancy symptoms, such as nausea or breast tenderness, relate directly to the pregnancy hormone hCG. This hormone increases during the first months of your pregnancy, and your symptoms often get worse.
After around 8-10 weeks of pregnancy, the hCG hormone decreases rapidly and with it, your pregnancy symptoms. This is normal and has no negative effect on your developing fetus.
Your doctor can confirm the well-being of your fetus by checking the fetal heartbeat.
