Juice Feast results in post-meno period

I watched the YouTube video by Dave the Raw Food Trucker. During Number 3 of 3, he mentions knowing post-menopausal women who get their period when juice feasting somewhere between Day 10 and Day 22. On Day 14 I got my period! I am 63 years old. But I'm concerned because my husband is in his forties. Does anyone know if I could get pregnant? Do I now have to use birth control? Tweet
