OKAY SO- I started bleeding the other day, period possibly or I assumed, and had a sudden effexor withdrawal the other day and noticed I'd stopped bleeding. I'm not sure if the bleeding was my period or side effects from plan b, but it seemed too heavy to be plan b. I'm asking if anyone else has noticed issues with their bleeding alongside Effexor withdrawal? If so please tell, I took a pregnancy test and it said negative but Im going to take another today. I'm trying to track down what caused this. Any possible answers would be extremely helpful. Extra: I came off of a birth control about 4 months ago as well, which I was one for about 7 years.
