Hello everyone! I started norethisterone on 2nd March and did 10 days and I started a bleed on 14th March. I have my base scan tomorrow. I am excited and hoping I can start the Stim injections. The reason for this post is . . . I have horrible period pains! I never have this bad, It is constant and i could hardly sleep last night for the pain. Did anyone else experience this with norethisterone ? xxxx
