It's definitely a thing, that was happening to me on most cycles. I'd even get every O symptom. I was temping and sometimes my temp would even rise for 2 days then drop again. I'd O a week later. It was so frustrating.
If there was one thing I learned from all the years of trying different things it was that I should have had my hormones tested first before messing around with anything and everything that promised to "balance my hormones". I went to a fantastic naturopath (who was actually the one who got all my blood tests ordered at the GP and discovered all the medical issues I had that doctors had never bothered testing) and she was able to tell me which supplements I should take and which to stay away from. I really think my self diagnosed trial and errors with herbs might have done more harm than good at the time unfortunately 😕
