4 positive OPKs this month

Micro • Tue, Oct 25

I think something is wrong with my cycle. I'm coming off of an Chinese. Medicine herbal blend which caused me to have an abnormally long cycle last month (43 days and normal for me is 27-29 days). Anyways, this month I had +OPKs on CD10, CD13-15. This isn't normal for me. Is something wrong?
