My period was late and started 4 days ago. But lately I'm having these weird butterfly sensations in my stomach that I've never felt before. Gas maybe? It's like little flutters last time I took a hpt wqs day before period due and was negative. I don't have a really heavy period but it's like a light to medium. I know alot of woman bleed during the first trimester. I never have, and it's during me crazy! I haven't tested since I lost hope obviously. But I kinda have that feeling like "what if I'm pregnant and bleeding"? Anyone go through this!?
