I had a contraceptive implant put in a week and a half ago, and have constant bleeding since?

Hi there. I had the contraceptive implant put in a week and a half ago, and have constant bleeding since. I have mefenamic acid at home, and I heard this could help. My only problem is I also take fluoxetine and I’ve heard it’s a contraindication. Could I stop my fluoxetine for a while and take the mefenamic acid?
