Help!!

Me and my s/o have been trying for two months to get pregnant. I have all the symptoms I was due for my period last week and a few days before it was suppose to come I started spotting on and off for a couple days and it just stopped I have gained 5 lbs in the past two weeks none of my clothes fit anymore but test are coming back negative. Could it be to early to show up? I just don't want to get my hopes up! I have been off birth control for two years. I feel little flutters in my lower abdomen but I have felt those since my daughter was born 5.5 years ago... I feel like we are trying to hard! Any advice would be wonderful. Tia
