Gram positive bacilli have been known to be associated with an IUD, and it is usually due to clostridium species of bacteria. These can usually be treated effectively with penicillin or penicillin family antibiotics. If your pregnancy
is otherwise doing well, and the blood clot is currently absent or small, you should be able to treat the infection and things should be fine. Moniliasis
just means that there is some yeast which can also be easily treated if it is symptomatic. The bottom line is that you should talk to your doctor about getting this infection treated, and you and your pregnancy should be fine. I hope this helps, please let me know if you have any more questions.
