I got a positive test about a week ago and two days ago I started spotting, it was a brownish color. Today it has turned into more red & it is a start and stop type of bleeding not even enough to need a tampon or anything & I am having really bad cramps. Doctors haven’t determined how far along I am yet but implantation bleeding happened on 9-5 & 9-6. From that I am assuming I am 3 weeks and 3 days. But I am scared and due to work I don’t really have the time to go get checked out unless I go in the middle of the night which then I won’t get any sleep for work the next day.
