Hi all, the months I am not TTC as my partner is working away I don't get any spotting, (maybe a day or 2 before my period). The months I do the spotting starts around the time implantation should be and lasts all the way up to my period. Could failed implantation cause spotting? Every month I hope it's implantation bleeding but it never is! I'm 34. Been trying for about a year. My Doc doesn't seem bothered about testing me for low progesterone which I here can be a cause of spotting. Thanks for any advice
