So I been married now for over a year we been ttc the whole time and I feel in my gut something it's not right my period are now lasting 2 weeks I have gone to doctors asking for help but because I'm young they seem to never take me serious I have been waiting for my ultra sound appt. For 3 months now and nothing where do I go from here. Where can I go to get the necessary help and actually be taken seriously
