Long Period on Slynd: When to Worry?

@Kingswife well, the medication that I mentioned (Slynd) is a birth control, It is just progesterone-based, rather than being estrogen based or a combination based one. And it is supposed to help me regulate my hormones and my period and all of that. I'm not sure if it's just that it's only been a month so I'm still waiting for it to regulate everything, or if there's something else going on. A friend of mine whose mom is a PCP said that she didn't think I should worry just yet, but I wanted to get some more opinions before I made a decision. I was also wondering if, since I tend to run a bit anemic and take an iron pill anyway, if given how long and heavy it's been should I take another one for a couple days? I'm just about decided if this is still going on by Wednesday I'm going to call them, but I was curious to know if anybody else had a similar situation happen when they started a progesterone-based pill.
