Need advice

I'm afraid I'm gonna have preeclampsia, I keep waking up with my eyes swollen almost shut, my feet (especially my left) hurting for being so swollen, my last doc appointment she told me my blood pressure was high, my mom had it with her first child, and I have so many headaches... I don't know if it's genetic or not but it makes me nervous that my mom had it. by the way I'm 27 weeks and 4days someone. If someone knows something about this or had experience with this please let me know!! Thanks!!
