Tricky situation!! This has never happened to me before

So I began taking Vitex on July 1. I'm irregular so my cycles can last anywhere between 45-69 days. Since starting Vitex I didn't immediately notice any changes. I ovulated last Wednesday, and 2 days ago (4dpo) I started experiencing mild pelvic pain/cramps/spasm (literally all in one) but very mild and light soreness in my nipples. As of today (6dpo) I am experiencing very very bad pain/cramps/spasms in the pelvic and lower abdomen are, also a stretchy sensation. According to glow my period is to begin on Tuesday, but I never get period cramps this early. It's usually the day or a very few hours before I bleed. Since my psychic told me that I will be pregnant in October, I decided not to test before then 😖 so I just wanted to know if anyone taking Vitex or not have experienced similar symptoms before their BFP?! Thanks ladies 💚💛💙
