I been trying for 2 in a half months to get pregnant and I been having a lot of synthoms nausea, headaches, cramping , lite period I usually last 7-8 days but only lasted 4 days not very heavy it came out negative since that day I still been trying . Now I'm having the same synthoms still but worse it's hard to get out of bed sometimes but my breast dnt hurt yet. I should start my period February 15 . Am I pregnant or not what should I do?
