Vitex and BFP

Sha
I just got a BFP. I have been taking vitex for a month. I didn't get my periods when it was due and I thought vitex was messing with my cycle and stopped taking. 5 days later (today) I got a BFP. What should I do? I have heard that stopping vitex can cause mc and also taking it can be an issue. Anyone has experience with this?
