What do I do?

I thought my period came on today. Like I wiped and I seen red. So I put a pad on. I check later and nothing there. I wiped. Nothing there. Like u think it’s delayed? I took a test 2 days ago. It said not pregnant. Glow said I’m due Wednesday. But I’ve been having hip pain. Cramps. Normal period stuff. I even did the tampon test like I did last time. Last time I was pregnant. This time. Idk. Like when I put the tampon in it was there. Just like last time. Could it be delayed. I just had my baby in August.
