Brown discharge... Is this normal??

Candice • I have an amazing 4yr old daughter, who was a rainbow baby! We are now expecting a rainbow baby, another princess!
I am 7 weeks along and used the restroom then when I wiped there was brown discharge/spotting! It looked like what you get at the beginning or end of your AF. I haven't been cramping but it is really throwing me off. I have had 3 previous miscarriges and I'm so scared this is the start of another! Anyone else have this... Please tell me it's normal!!
