Pink discharge after vomiting! 7 weeks

It's about 1 a.m. and I just woke up with the worst nausea I've had yet. I ran to the bathroom and starting getting sick. I'm not sure if I am the only one but when I throw up my body will tense up and try to expel whatever it is out of either my mouth or the other end. After I was done being sick I wiped myself and noticed some light pink discharge. Has this happened to anyone? Was everything ok?! I'm freaking out that my body just pushed so hard I'm making myself miscarry. I'm so scared.
