Not enough info.... You should consult a HealthTap Gyn, do a prime consult or see your OB/GYN.There is not enough info here to answer you.Some things you will need to know, are when was Oct period, have you missed Nov. one, was the bleeding nl, preg test. This could poss be a very early preg loss ("false preg"). They're actually very common & one event is not predictive of future losses. You Likely need a Gyn exam.
