Anyone experience this while taking vitex??

Ky 8-15-17👼🏼 & 10-28-17👼🏼 Pregnant with my🌈💕

I've been taking vitex for 5 weeks now. I bled from last Monday thru last wednesday/ thursday. And it was VERY light. Usually my periods before taking vitex were 7 days long and a medium flow.

I just started bleeding again Wednesday night. Me and me husband had sex and my cervix felt tender when he would hit it. Then we noticed I was bleeding. So then yesterday I checked my cm and it was bloody stretchy cm. And this morning when I woke up I wiped and there was blood and a little bit in my panty liner. Is this another period?? I'm on CD 12 also. Have you experience anything similar while taking vitex??
