Cramping at 4 weeks

Jenna

I took a pregnancy test a little earlier then when i was supposed to get my cycle and I came back pregnant. I went to the doctors to confirm and she did indeed tell me I am pregnant, So for the past few days, I have been cramping. My cramping isn’t super terrible and it’s a little lighter than when I am normally on my period. I haven’t been bleeding or anything just cramping. Today, the cramping has gotten a little stronger but still not as strong as when I usually cramp. I am a little worried but I’m not sure if I’m overthinking it. This would be day three or four that I would have had my period . Is anyone else experiencing this or have they experienced it before?
