Hi, they put me on it cause my period got down to only one day. Then I was only on it for one month because it made me not have a period at all. So I quit taking it and it started back and now I'm up to about 2 1/2 days now. I'm thinking I have a hormone prob. I have all kinds of issues cause I had my son 15 months ago and still lactating, and never breastfeed. I do believe it is normal for you, since you have had longer periods.
