A bit of blood, thought she was having her period, got pregnant.

When a sexually active woman has an obvious history of menstrual arrest, even if she has no history of menstrual arrest, when the amount of vaginal bleeding is significantly reduced compared with the usual menstrual flow, or even shows a little blood, attention needs to be paid to it. If it is necessary to rule out the possibility of early pregnancy, you need to go to the hospital for further examination. You can perform an ultrasound examination or a blood HCG test to rule out whether it is drip bleeding caused by the implantation of a pregnant fertilized egg or a period. Generally, after HCG blood examination, it can be diagnosed as a period or pregnancy. If pregnant, it generally needs to be treated with fetal protection.
