hi katxenfreundin, answer to ur question no u can't get pregnant without a period as u would need to produce eggs. each month ur womb making a lining which is the blood then if u don't get pregnant ur womb sheads that lining which is wen u get ur period. u only have a certain amount of days when ur fertile to make a baby. best way is to but opks ( ovulation perdition kits) this way u can tell. but u wud need to talk to ur dr about ur periods he may give u some tablets to help bring them on... I'm still getting mine and I've been on gear for 6 years I've had 2 mc ( miscarriage) if u need further info plz msg me. I do know a bit about the reproductive system. x
