am I crazy?!

Ma

I am only 8 weeks but every now and then I get a couple thuds in my stomach. they arent huge but definitely noticeable! it's not gas cause it's right above my vagina area. gas for me usually goes from around my hips and up. this is my secind baby, the first started kicking at 15 weeks and I could feel then even with an anterior placenta! could it be the baby already?
