6 weeks pregnant, spotting, and scared

Several times yesterday I wiped and was spotting little bits of brown. I also had small mild cramping on and off. Then at 6am this morning I woke up to wetness and went to the bathroom to wipe and I had a bigger amount. It just looks brown in the picture because I'm taking it two hours later but it had some pinkish in it before. Has this happened to anyone else? I'm so nervous. I couldn't go back to sleep. I know that sporting can be normal, and you shouldn't be alarmed unless it's heavy bleeding and significant cramping according to my doctor, but I'm scared it's going to get worse
