Tmi..no pic

I am on zofran and I am SO CONSTIPATED! (I'm 10 weeks) I literally am stuck. I sit on the toilet for half an hour at a time trying to get it out and I end up having to "suck it back up"-sorry for the tmi. I just had prunes and Metamucil. Has this happened to anyone else. I may end up calling the midwife on call (since it's Sunday) to see if I can get some sort of softener. I'm just worried it's impacted and pushing a ton will not be healthy. Ugh. Oh the joys!!!
