@Rachna , My doctor did blood test in Jan month n suggested me to take vitamin d3 tablet. I am taking vitamin d3,iron tablet along with pre natal. Me too, in my first pregnancy I was very active. I used to walk 1 hr in Mrg and 1 hr in eve. I used to sweep n mop floor every other day during my 8 th month. This pregnancy I couldn't walk out properly. Doing normal household chores make me exhausted. Feeling tired. Getting frustrated to see messy house. My doctor suggest to take calcium n magnesium tablet when I feel leg cramp. I took once or twice ,when I was in india. Not now. Getting sleep in nite,is big problem now. I sleep only in day time,after sending husband n elder one.
