First pg, twin girls, nausea/dry heaving that lasted 18 weeks, though it wasn't nearly as bad as it likely would have been due to the fact that I wasn't working and had no other children. I laid on the couch. A lot.

Horrible heartburn from implantation til delivery. Horrible round ligament pain from about 16-20 weeks. Horrible belly itching for the last 10 days or so. Pre-eclampsia at the very end, symptoms starting at 37 weeks.
Delivered at 38w3d by scheduled section.
Second pg, singleton boy, some nausea, very tired. Twins were 4 months old when I got pg, so I was tired to begin with.

Heartburn similar to twin pg, though I took much better meds to control it since they were concerned about long term damage with back to back pg and such severe reflux.
Absolutely no ligament pain whatsoever, though I was obviously still stretched out from previous twin pg. No pre-e.
Membranes ruptured at 38w, ERCS.
Third pg, singleton girl, put the other two to shame. HORRIBLE nausea/dry heaving with a break between 26-29 weeks. Otherwise, I thought I was surely going to die.
Ligament pain from 14-24 weeks, much worse than with twin pg even. Heartburn not *quite* as bad, but again, I took pretty good meds to reduce risk of long term damage.
Pre-e much worse with this pg with symptoms beginning at 35 weeks. Delivered at 37w1d by ERCS due to escalating pre-e.
