I have been on Otezla for about 7-8 months. My periods are starting sooner each month. I was almost always right at 28 days, then starting in March of this year it was 3 1/2 weeks, then 3 weeks, then 2 1/2 weeks, now I just started again today and my last period was a week and a half ago! If this rate keeps steady I'll be on my period every single day. The Otezla is the only thing I can think of to be causing this. I will obviously be making a dermatology appt and an OB/GYN appt, but I didn't know if anyone rise was experiencing this.
