hello I had a few questions to ask. my periods are usually irregular and come twice a month. I last had my periods in december of 2013. ( period dates Dec. 15th-18th & Dec. 29th-31st 2013 ) I went all throughout January 2014 without one and barely started my period today February 5, 2014. Is it possible I can be pregnant? I ve taken two pregnancy tests that came up as early neagitives and went to planned parenthood yesterday for an appointment and they told me it was neagitive. I have been feeling some symptoms such as heacdaches, backasches, nausea, vomitting, fatigue and tired. It s funny, because even though the tests say neagitive I still feel I could be pregnant.
