Eat nutritious food drink lots of milk and as its 7 to 8 weeks will get better. Understand on the sick leave part. If can go to work and tell them you're sick and in pain atleast they will understand that you came to work and excuse you for 2 days. If not apply leave n take rest. But try to keep mc for second trimester. For 3rd trimester confirm can get hospitalization leave.
