<s>[INST] hello, Ive recently had IVF treatment that resulted in pg and OHSS. I had 2-3l of fluid in my abdomen as per US and have enlarged ovaries (right one 115mm x 60mm, left 93mmx74mm. There were still some follicles present when i had the US (1/6). I am feeling OK now, just noticed a lumpy feeling in my right side of the lower abdomen. I am worried about this. Can this be the enlarged ovary that I feel? its just under the bellybutton on the right side [/INST] Hi welcome to Chat Doctor. I have gone through your question. You have lumpy feeling due to very large ovaries due to enlarged follicles and this much fluid may be due to rupture of follicles as a consequence of HSS over stimulation. So I would advise you that stop treatment for 1/2 cycle and consult gynecologist for further treatment. Hope I answered your question. Would be happy to help you further. Take care. </s>
