Actually yaar, constipation is a huge issue because of those iron tablets. I started eating oats, papaya (only if doctor allows or stick to safe fibers like apples), and lots of green veggies. And drink lots of water, that's the ultimate key!
Constipation can cause a lot of strain which can feel very scary, especially if you have had past losses. Please drink lots of warm water, eat fresh green vegetables, and take things very gently. Do consult your doctor if the straining becomes too painful, as keeping yourself safe is most important.
Dealing with constipation when you want to eat all your favorite foods is so annoying! I started drinking a glass of warm milk with a spoon of ghee at night, and had lots of fiber-rich fruits like apples and pears. It kept my stomach clear so I could enjoy my spicy cravings without any worry!
I totally understand how uncomfortable and frustrating this must be for you, sweetie. Your body is going through so many changes, so please don't be hard on yourself. Try eating some high-fiber foods like soaked prunes or drinking warm water, and I truly hope you feel better very soon.
