I wanted to know if exercise will affect my period or ovulation? I recently have had abnormal periods due to loss of a pregnancy at 20 weeks with a d&c performed. My first period came back 35 days after surgery and the second just came back the other day, 47 days after the previous period. I have waited the treen months like the doctor told meand we are for sure ready to start trying again. I like to get on the treadmill and exercise, but I am scared that it will affect my cycle. I did not know that if alot of exercise, where I would sweat alot can cause my period or ovulation to be even more screwed up or skipped. I have heard that alot of heavy exercising can delay your period, I did not know how true this was, does anyone know? I do not want to risk skipping any more cycles and ovulation cause I want to ttc as sson as possible. i am confused????
