Thanks for the query.
The chance of pregnancy
is less as your blood test
for pregnancy is negative.
Usually the blood test is said to be negative when the HCG levels are below 5.
The low HCG levels you had in the previous pregnancy could be less for expected gestational age
but may not be as low as below 5.
After delivery the menstrual cycle may take some time for regularization and that depends on factors like lactation
, hormones, Hb level etc.
So as you are having anemia start taking iron supplementation, and take tablets for withdrawal bleeding with your doctor's advice.
