Hello,
Welcome to HCM and thanks for asking your queries. I will do my best to solve all your doubts.
First of all i want to tell you that because you had a history of
abortion, this
pregnancy is very precious. Your doctor has rightly prescribed you
susten tablets, which contains
progesterone and its very effective to maintain pregnancy during early days, specially during 1st 3 months.
Coming back to your next question, normal or CS delivery will not depend on this tablet, but it depends on many factors, which are to be identified by your gynceologist and its not possible to predict delivery type in early days, so for that you will have to wait for few more months.
Susten tablets are not
steroids, so no need to worry about it.
These tablets will not at all affect your baby in any ways, so remove such doubt from your mind.
Coming to your last question, i am really not sure why your doctor has advised not to take spinach, because spinach is actually a very good food during pregnancy, because it contains iron and many
vitamins in it, so you better ask to your doctor to clear your query about spinach.
Hope this much information from my side will solve most of your queries.
