Hello B.J. Has she ever been on birth control pills? I was on the pill for 7.5 years and they really messed up my cycle! I have been off them for 1 year and 7 months now and my cycles still need a little jump start. I have used Red Raspberry Leaf tea and it has worked everytime for me. I drink the tea double strength for about 3-4 days 3 times a day between meals. It brings on ovulation and then my period 2 weeks later. My husband and I are ready to start a family so I have been charting (taking my temperature every morning) to see what my body is doing. I have learned a great deal with this. I would suggest the tea but also has she ever seen a gynecologist? She may have a condition like endometriosis, PCOS, or something else. Once you know that then you can plan your treatment accordingly. As far as it being psychological I would say yes it could be a part of it. I know that happened to me once. I didn't have a period for 8 months because I was constantly thinking and worrying about it. Well I hope that helps some. I wish you the best. Take care!
