Can I feel the baby yet?

Lisa

I’m currently 14+1 and last night I woke up at 4am and was having bad back aches, I laid on my back and put my hand on my uterus area to rest. I felt around and I could feel a firm lump around the size of what the baby would be (a lemon) is this the baby/sac I can feel? Is it possible to feel something 3 and half months along?
