I was not getting my period since last 2 months and taken crina ncr 10 mg tab for 5 days but still not getting my period. Then I had pregnancy test its negative. After 10 to 15 days I had again pregnancy test this time its positive.in ultrasound I was 3 weeks pregnant. Now I am 6 months pregnant. So my question is it harmful for me or my fetus to take crina ncr 10 mg tab for 5 days during 3 weeks pregnancy. Please provide the answer in details.
