Usually I have only one day of heavy bleeding with some clotting and my period is 4 days long.

So I started my period 1 day early (whatever that happens sometime).. it was heavier than normal. I had heavy bleeding for 3 days with large clots (I was a little concerned about that and thought maybe I was anemic but I’m taking prenatal so I doubt it) Then 1 day of nothing. Spotting yesterday (after having sex) and bleeding again today. I am TTC and taking prenatals so I’m not sure it that affects things
