feeling things getting scared 😰😰😰

So I was trying to go to sleep last night and I was sleep for a good hour then I felt the most painful cramp ever and then i looked down and saw something move and I was thinking I'm only 8weeks it can't be the baby an I was to scared to look it up and today my nips were tender as a mf I had to put ice on them to cool them down they were red too I'm scared I don't understand does anyone have any advice to what's happening to my body
