So Ive been on my medication now for two months. First month I was on Adderall XR 10mg (once a day) - and my period was about a week late, but otherwise normal. I was then upped to Adderall XR 20mg (once a day). I got my period, and instead of only lasting about 5 days as it normally does, it lasted about 8-9 days of fairly light bleeding. Now, about 2 weeks after the first day of that - Im bleeding again (and have been for the last probably 3 or 4 days) and its fairly normal to what Im used to... assuming it will end in a day or two.

Im not on birth control or anything. Is this normal? I made an apt to see my doctor on Monday, but still. Any cause for concern?

Well mine was very late this cycle. I have been taking Adderall for 3 months or so. On 25mg of xr right now. I don't remember when my last period was, but last week my husband made me take a pregnancy test, so I must been pretttty late haha! Then this week it came. It is normal so far. I hope it doesn't last 9 days!!!
