My first day of last menstruation was nov. 27,2011..hpt's were negative..i have a cycle of 28-32 days..on december 10th and onward,i had a feud with my boyfriend..we only have sex on the 4th, 6th, 8th and 17th of december..i was stressed..is it possible to miss my period altogether? Because it is very unlikely for me to have a missed period, because i have a regular period since menarche..and lastly, i had a spinnbarkeit 3 days ago..what does this mean? I am delayed about 2 weeks..Please help me..thank you very much..
