<s>[INST] Hi I am 31 yr olf ttc for 8 mth. Periods are ranging from 26 days to 30 days ; I got HSG and Day 3 baseline test done ; Ovaries and eggs are good ; HSG indicated right tube bloakage and left tube dilation (20% chance); But left may be clean is what the RE said; I did the test on CD 10 May 17 2013 ; I am on CD 17 today with mile spotting and acute pain in lower right side of the abdomen ; This pain normally comes during menstrual cycle. But this side has been paining now for like 3-4 days ; It comes for about 20 min and goes away ; Occasionally my legs ache too. What could be the reason for the same . Please let me know. [/INST] Hi, Thanks for the query. As you are having right side tubal block and now having pain on the same side, better to consult gynecologist and get examined. As you are trying to conceive and as sometimes you are having shorter cycles, though rare there is possibility of tubal ectopic pregnancy. The other possibility for pain is pelvic inflammatory disease. Consult gynecologist and go for ultrasound to find out the possible cause.
