Hi! I had a cervical biopsy done back on 11/2/15. It was my 3rd time having one, and my DR said that this time she did the equivalent of 3 biopsy's, and it was all a pretty painful experience. Much more painful then the previous two. Any ways I got my regular period on time a week after the biopsy. However my December period was 3 days late, and was just dark blood and done in about 24hrs. I am typically always right on time, and bleed for 4 or 5 days. Now this month I am two days late so far. Both last month and right now I am feeling like I should be getting my period but no sign. I have not taken a pregnancy test yet, but I do not think that is the case as I am on Yaz birth control, and have not had any sexual activity since before the biopsy. The results of the biopsy were CN2, and my Dr. recommends that we revaluate next November, and probably schedule a LEEP procedure. Are these symptoms something that I should by really worried by?
