I only took the iron and calcium tablets that my doctor prescribed. For anything else, even a headache, I always called my clinic first because I didn't want to take any personal risks.
Honestly, you don't have the time to deal with side effects, so keep a list of safe medicines approved by your gynac on your fridge. Never self-medicate, just message your doctor for a quick prescription.
My pregnancy tracker had a whole list of safe ingredients, but it also warned that every pregnancy is unique. It's always safest to upload your symptoms on your hospital app and let the doctor prescribe.
Apart from basic paracetamol for mild fever, don't take any medicine on your own. For small issues, try hot water steam or ginger tea before jumping to pills.
In our family, we use turmeric milk for cold and cumin water for digestion instead of taking pills. For any proper medicine, please consult your doctor first as self-medication is not safe now.
I tried to avoid medicines entirely and focused on light prenatal yoga and daily walks to keep body aches away, of course after my doctor's green signal. Only take what your gynac prescribes.
Looking back, we worry so much about pills! Generally, only basic paracetamol is considered safe, but even for that, just confirm with your gynac once to be completely stress-free.
