What are the contraindications and the use of angelica?

Good evening, a few weeks ago, after some research on angelica, I started taking it – the dose indicated on the package of 4 capsules a day – for about ten days (11), but I had read of cases of hypersensitivity to the herb in question , which could cause bleeding, and unfortunately it happened. I took it to regulate hormones and to aid digestion, suffering from heartburn. I stopped it immediately after noticing some blood loss, the losses stopped, apart from sporadic amber spots, it gives me the impression that I have anticipated my period, even if I have not had major losses anymore, but I seem to be in pre cycle. Among other things, together with the angelica I had taken a vivin c, which being a fluidifying agent, I’m afraid that it has further worsened the situation. I just wanted to have some more news about it, if with the next flow everything will be back to normal if I have to panic. I hope I explained myself well, thanks and best regards.
