I see. You're menstrual period is abnormal. 6-7 month delay between menstrual periods for a 23 year old woman is not normal. I'd recommend that you visit your OB-GYN, however, before you start dosing yourself with supplements that support hormones.
What is Estroblend?
Estroblend is a vitamin and mineral supplements that support estrogen metabolism. This brand is produced by Wal-Mart, Inc and is a line of products formulated for women to help symptoms associated with menopause, including, cosmetics, lotions, creams, gels, sprays, supplements, drinks, lip balm.
As you're not in the age-range for menopause symptoms, I suggest that you first get a diagnosis and seek better understanding of what's going on.
