Hello, I need advice, my last mens was 24 June 2010, I have brownish spotting on my day 11 of cycle day 12 I had ultrasound it shows clear follicle in right fallopian tube, the day after I had ultrasound it shows gestational sac so my Dr. request for Beta ChatDoctor level it was high 1750 on 5 July 2010 !! then she assure me that is pregnancy. I was wondering how to have positive pregnancy in my day 14 of cycle, my Dr. prescribe for me duphastone 10 mg twice daily. after a week I repeat Beta ChatDoctor result was 8900 on 12 july 2010. I was feeling nausea and regular signs of pregnancy. on 19 July I went to do ultrasound to check for the fetus. nothing appear and suspected ectopic after that my Dr. asked me to repeat Beta ChatDoctor 28000 so I was admitted for laparoscopic operation for ectopic pregnancy in my left side fallopian tube was removed. I was have no pain but with continuous brownish spotting. Im wondering how the first ultrasound shows folicle in the right side is there any explanation??? Thanks

### output:

Hello, I have gone through your query and understood the concern. I will be able to comment further if you can furnish me details of the sonogram reports and also the operative notes. It is quite rare that when the follicle was visualized in the right tube, ectopic was detected in the left tube. This means the fertilized egg instead of travelling into the uterus, traveled via the pelvic cavity into the other fallopian tube, which is a very rare phenomenon. It is possible another follicle in the left tube was missed at the time of the initial scan. Release of multiple follicles simultaneously from both the ovaries also is a rare phenomenon. Hope your query has been answered. Take care.
