Severe constipation

Beth
Please someone help!! I've been constipated the last two days
Now it's impacted and I can't get the poop out. I'm nauseated and feel like I could puke at any time. My stomach is killing me
I'm 10 weeks pregnant
I've been drinking 80 ounces of water the last two days, eating yogurt, drinking prune juice, and I tried miralax last night. I just want to get this hard mass out
Any suggestions?
