Hello, im a 20 year old woman and several times have had pregnancy scares. I have been feeling somewhat dizzy the past 2 weeks and my stomach always seems to be upset. My stomach is also tender to something as little as an arm layed across it. I dont base taking a pregnancy test by missed periods because I have a unique irregular period; I get my period for about 4 days every 3 months. Im hesitant to go buy another test. What are some other reasons for feeling this way? Thanks! -Michelle
