I recently found out I was pregnant and I’ve been having cramps (not like period) just dull mild pulling pitching cramps. Today I woke up and I have a brown spotting/discharge. Is that normal? Has anyone else experience that after finding out they were pregnant? I didn’t have any implantation spotting and Bc I already found out I’m pregnant and 5 days passed my missed period I’m concern.
