If you have a little period and then lose it, in this case, you must be alert to the possibility of pregnancy or to exclude the possibility of ectopic pregnancy. It is necessary to go to the hospital to check the blood HCG. If it is positive, it is recommended to check the blood HCG again every other day to see if it doubles up from the original one to determine whether it is an intrauterine pregnancy or an ectopic pregnancy.
