first month using vitex... bd time?

Dejah • 22 y/o TTC my rainbow baby 🌈👶🏽

[last test is from today]

i kinda know the answer but i’m just super shocked because last month the transition was so gradual 🙉. has anyone taking vitex experienced a similar jump between negatives and peak?? my ovulation day was supposed to be on Wednesday which is 3 days from now.
