I felt so overwhelmed by all the daily tablets in my first trimester. If you are talking about regular prenatal vitamins, I found taking them after a light meal helped reduce my nausea. Please consult your doctor for the exact instructions so you feel safe.
If you are talking about the mountain of daily vitamins I've been swallowing for 8 months, just wash them down with lots of water after a meal, haha! But if it's any other pill, seriously, don't play guessing games and ask your gynac right away.
Please don't buy or take any pregnancy-related pills without a doctor's prescription, as wrong self-medication can lead to expensive emergency hospital visits later. Get a standard prescription from a government or budget-friendly clinic. Prenatal vitamins are usually taken daily with water after food.
Let's be clear—if you are talking about abortion pills, you must consult a gynecologist immediately; never self-medicate. If you just mean daily pregnancy supplements, take your iron and calcium at different times of the day with water as recommended by your doctor.
If you mean prenatal vitamins like folic acid and iron, just take them after lunch or dinner with water as your doctor suggested. But if you mean medical termination pills, please never do it at home without a doctor's prescription. Always get a proper prescription from your local clinic.
