Hi. I Need Help. I Am 19 Years Old. And I Have Had one pregnancy a year ago that was terminated at 5w 1d. Well My last normal period Was On December 13 on December 26 I Had unprotected sex and my period was due to arrive jan. 10 on the 10the I had an unusually light flow which was completely gone by the 13th I have never had a flow so light or short. Previous to the 1/10 I was having unusual symptoms such as extreme fatigue low left back pain dizziness and lower left abdominal aches. On the 9th of januaey I did a home pregnancy test which came back negative on 1/17 I had an ultrasoun at my local clinic the tech saw was she thought may have been a 4w 4d gestation sac so she did blood work witch came back yesturday 1/22 negative I took another home pregnancy test and still negative but over the last few days I've been having a low cramp which I never had mid cycle. Could this be a actual pregnancy or a cyst or other condition?
