Anxiety/OCD worse day 16 after increase

I increased from 50 mg to 62.5 mg and been on the increase for 16 days and my anxiety and OCD has gotten so bad the last few days and especially today that I feel the same way I did before starting Zoloft, I actually was able to do stuff and I’m scared that it’s just not working anymore.
Did anybody feel like this on such a small increase?
