Okay last month December 10, 2010, my husband went out of the country and the last time we were sexually active was December 9 the day before he left(we always use a condom, always use it the proper way. I am not on birth control). My husband stayed until yesterday Jan. 25th and went to just visit family. It was not easy for me and yea I was stressed a lot with him gone, I was scared to stay alone even though I have my two toddlers with me. Well I started my period December 15th which lasted until the 20th. Well January came and on the 14th I got period pains just like I was about to start, I also had them early on the 15th and then around lunch I had pain on my left side just like I get when I ovulate and it lasted several hours just like when I ovulate, I even had some stretchy type discharge but not much. I am now 11 days late for my period. I got even more stressed out as seeing my period was not showing up. I have been very stressed out before and never had this issue. For the past 6 days I had a cold(mainly head cold.) I may get slight crampish feelings every now and then but for the most of it I dont feel my period coming on. I took a pregnancy test on January 21st and Janurary 25th which were both negative. I did not think I was pregnant because my husband and I are extremely careful but just took a test because I have never been more that 4 days late before. My period usually skips around a day or 2 and 4 days being the most. Just wondering what is going on. What are your suggestions.
