So I started my period Tuesday morning. This is my first period or anything since stopping birth control November 25th. Before when I started my period it started out light, heavy for two days, then light again. But not this time! Now it’s started out heavy and all 4 days I’ve been on my period it has been bright red and VERY HEAVY and having a lot of clots. Just wondering if this is normal for it to be this heavy for this long. I’m not having any cramps just bleeding like crazy.
