What medications can I take to increase chances of getting pregnant. I have taken Angus Castus to regulate periods. What are the success stories on taking clomid to regulate periods. I have very short cycles (period every weeks), GP done blood tests and vaginal ultrasound which have come back normal. I was on depo injection for 2 years which stopped my periods completely. Now it’s been a year since I came off it and got periods from hell.
