I'm 7 weeks and 2 days pregnant and I just found out that the yolk sac is measuring 7.8 mm in diameter. I'm a bit worried about what this means for my pregnancy. Is this something I should be concerned about, and is there a chance the yolk sac size can return to normal?

A yolk sac diameter of 7-8 mm at 7 weeks and 2 days of pregnancy is slightly larger than expected, as the normal diameter is usually around 3-5 mm by the sixth week. This could potentially indicate a problem with the pregnancy, such as an early sign of miscarriage. However, it's essential to note that a single ultrasound measurement is not conclusive, and your healthcare provider may recommend a follow-up ultrasound to reassess the yolk sac size and check for any other signs of a healthy pregnancy. consult gynaecologist

I'm 19 and not married. I'm currently 10 weeks pregnant and I'm wondering if I can have a surgical abortion without needing my parents' permission. Would a doctor be able to help me with this?

In India, the Medical Termination of Pregnancy (MTP) Act of 1971 allows for abortion up to 20 weeks, but for minors (below 18), parental consent is required; however, as you're 19, you can legally undergo a surgical abortion at 10 weeks without parental consent; consult a gynecologist
