Just found out I'm pregnant

I found out yesterday im pregnant. I've done 3 clear blue tests which were immediately positive. Been fine all day just abit bloated and crampy but I've just been to the loo an noticed a light browny/pink strain through the discharge when I wipe . I'm only 3 weeks 4 days so I know it's early 😕 anyone else had this? I didn't with my last pregnancy but that ended in miscarriage at 8 weeks
