I'm 7 1/2 weeks pregnant I wiped myself this morning and noticed brown blood I wiped again & then it was red?

I went to the doctor for my prenatal check up and I was told GOOD GOOD NEWS! My baby is OK! My doctor said I was having implantation bleeding and that is normal for some women to bleed during pregnancy! Wooo.. I so glad my doctor said me and the baby were OK because for second there I thought I was having an miscarriage with no cramping..So I am relieved!!!!
