6 weeks from start of miscarriage and have been ttc for 4 (got neg preg test), no af so dont know if i have ovulated or not. At what stage would you start to do pregnancy tests? af will prob arrive this week and then all will be fine but am just worried about conceiving and not knowing dates etc, also if i dont fall pg but af doesnt arrive, how long do people leave it before they see gp? I know its early days but all these questions are whirling round in my head, any advice please?
