Have you spotted from anti depressants?

Two days ago I started taking Cymbalta. I only got 3.5 hours of sleep that night and felt really jittery. That same night I started to notice a tiny spot of blood when I wiped. I thought maybe I just scratched myself with my nail or something and didn’t think too much of it. Yesterday I didn’t take it just in case. There was a bit more but nothing too crazy. I went ahead and called my PCP, spoke with a nurse to explain what was going on and never received a call back. (I often have to call and remind them 🙃) I have a history of ovarian cysts but can typically feel when they rupture. I’m not having any cramps and I am 10 days out from my next cycle. Essentially, I am just wondering if anyone else has had the same side effect from starting Cymbalta. Thank you in advance!
