Cramping & spotting at 4 weeks....

🎀GirlMom 01/2023🎀
Last night I was having very intense pain in my lower abdomen on the right side. This morning I woke up and I noticed brown spotting only when I wipe. Then later that morning I saw 2 brown spots in my panties. Should I be concerned or is this normal? I'll be calling my OB this morning to see if it's normal or not... Just want answers before they open..
