OB had me on birth control for three months to regulate periods. They were very regular and very easy to clock, on time each of those three months but they totally EFFED ME UUUUP!!! I’ve been taking myo-inositol and watching what I eat but my period is late and tests have been negative. I got this stuff from sprouts. I hope it helps😫 I have all these pms symptoms and still no period. I need that sweet release only she can bring so I can just staaaart over.
