Bloating, gas, and low back pain on Day 1 of your period could be due to hormonal fluctuations, digestive changes, or the butter fruit milkshake you consumed. Here's what you can do:
Hormonal Factors: Progesterone changes can slow digestion, causing bloating and discomfort.
Dietary Impact: The milkshake might have caused indigestion or gas.
Other Causes: Endometriosis, ovarian cysts, or IBS could also contribute to these symptoms.
Next Steps:
Consider a Pelvic Ultrasound (USG) on Day 5-7 of your cycle to rule out reproductive issues.

Vitamin D supplementation to address your deficiency.
