Ashley • Been with my husband 12 years, but married Aug. 2015 :: we have two daughters 💗💗 :: TTC #3
So I've read about vitamins that you can take to hep regulate your period so here is what I started taking in hopes it helps regulate my cycles! 
Vitamin D3 1000IU
Vitamin C 500mg
B-6 Vitamin 100mg
Iron 65mg 
I take these 1 time a day! So I wil see if it helps regulate my cycles!! 
Anyone else try any vitamins that helped regulate their cycles let me know!!
