I'm not sure what this is.

My husband and I have been trying to get pregnant for the last 3 months to no avail:-(. Each month I test I get a negative test result. My period on the other hand has been light. It still lasts 4/5 days but there's been an absence of clots. I'm just now getting off my period for this month and it's even lighter than last month. However for the past week I've been feeling "flutters" on my left side but I dismissed it as gas. Tonight I'm lying down on the bed talking to my daughter and I felt movement that definitely doesn't feel like gas. Even as I'm typing now I'm feeling it. Please tell me I'm not imagining things!! I'm about to schedule an appointment this week with my ob/gyn.
