Hi, I understand your concern. dull ache in lower abdomen is normal in pregnancy . but period like cramps suggest hormonal deficiency & abortion. This is easily managed by hormone replacement to support pregnancy. You have been already given it. Apart from this Tab. Duvadelan can be taken to control sever cramps. you should also, survival of pregnancy is good provided medicine schedule is followed strictly. _ avoid physical/psychological stress, - try to have good digestion/ bowel movements - eat light nourishing food with vegetables, fruits, milk, pulses, cerels. Thanks.
