I am 4 days late!! Going CRAZY over here. Taken 2 pregnancy test and they are negative. On cycle day 33 and I'm usually veryyyy regular. 29-30. I'm less concerned about pregnancy now and more concerned something is wrong and my period is not going to start which will affect my chances of conceving :( I have never had this happen. Anyone experience this ? I have been stressed. Dad is hospital. My doctor said wait a week and retest and call them back. Also brown spotting some esp after sex last night. Any advice or encouragement would be great ladies. Nervous and scared.
