Having had horses, dogs and parasites for a long time now, my opinion for what it is worth. At some point after a total physical breakdown, I took some of my horses' wormer at some point and I had a lot of worms come out. This was safegaurd, I think, I know it was not ivmecturine. I havn't gone there again, because so many things in my body were out of balance, from mostly the doctor meds(not the wormer). I admire your nerve, I havn't work up mine since.
Ivgold is a very strong wormer, give it more time before you dose again. You do it once a month to every six weeks for infested horses. It would be better for your body to wait a month, before doing it again. I bet you will see the effects of this worming for several days. It takes some longer to die than others. Then next month (if all goes well), do it again and you'll be able to kill all the hatching newbies the wormer wasn't able to kill (because they were eggs), and not being mature enough to have breed and produced eggs you will have wiped them out.
