Hi. Please do not worry. Betnesol is highly essential for baby s lung maturity, prevention from neonatal complications. This is had lot of research on safety and benefits so do take your second dose. Its followed as routine nowadays.
Better to consult your gynecologist. Sonography will be helpful here to access the amount of amniotic fluid level and growth of baby. Vaginal infection can also complicate the pregnancy. So get your check up done still if you continue to have problems you can consult online for proper guidance.
How many weeks are you pregnant. How is your appetite. Are you gaining weight. How is your bp. There are so many reasons because of which you can feel weakness. Without knowing details, its difficult to tell reason. In the meanwhile follow this 1. Don't take tea empty stomach. Eat something like a banana (if you are not diabetic) or any seasonal fruit or soaked almonds and a glass of water first thing in the morning (within 10 mins of waking up). No only biscuits or rusk will not do. 2. Don't overeat 3. Take your breakfast every day. Don't skip it. U should eat whatever your mother or grandparent eat in bfast. I mean to say whatever is your traditional food. If punjabi eat paratha, if belongs to south then take idli/ dosa etc.
