Hi, If this clinical presentation of spotting is not normal for you, a pregnancy test should be taken after another week by drawing blood. Unless pregnancy is excluded, do not go for withdrawal bleeding. If you are trying to conceive, getting a regular withdrawal bleed will not be enough. You need to ovulate regularly. For this, you can either use Metformin alone or in conjunction with ovulation inducing drugs based on the response to Metformin. Also, maintain a healthy weight and a healthy diet. Hope this helps.
