I have 4 kids already.... but I never had any issue with conception... my oldest I had when I was 18... my other 3 were born in consecutive years (2010,2011&2012)... my husband (my 4 aren’t biologically his) and I are ttc now... but not seeming to have any luck... so I’m going to start opks and monitoring my bbt but it’s all new to me... help!!!!!!
