Cassava twins

Anyone ever take cassava/cassava twins to hyperovulate? Did it delay period? So been ttc 2 year started taking this end of March and I believe ovulated twice as it says it can cause that and produce multiple eggs. I got 2 LH surges this month prob a week or 2 apart but my period was due 2 days ago and I don’t feel like it’s coming? I am never late I’m always early actually. I’m wondering if this messed up my cycle. It’s like eating 1 sweet potato/day. It’s natural and no side effects they say. I took a preg test 2 days ago and BFN. So I’m waiting to see if period shows up and I don’t want to take another preg test and get disappointed.
