Could it be

It's been 4 weeks sense my miscarriage and about a week ago I started feeling symptoms as if I was pregnant again. But instead of going away they seem to be getting worse definitely the being sick to my tummy all the time and I have random slight pains in my lower abdomen area on occasion but nothing that feels like period pain tho. Could I possibly be pregnant agin? I hear it's possible that people can end up pregnant this fast after one but it's not as common.
