Cycle day 55

So I have been pretty reg every 34/35 days for more than a year now probay almost 2 and I found out I was pregnant on Valentine's Day this year only to miscarry on March 13 and had to have a d and c since I was bleeding more than normal and after a week still hasn't expelled everything but I did end up getting my period back in April and had a period in May June and July as well ! I am now on day 55 in my cycle I have had a lot of egg white type cervical mucus and cramps here and there but nothing crazy I have taken several tests a few weeks ago when I was first late at one week and two weeks and all negative ! I just want my period to come so we can continue trying to conceive ! I have been known to ovulate late but this is alittle extreme ! Any ideas ? Im planning on calling the doctor monday and getting an appt so maybe at the least I can get meds to start my period back up !!
