Is it possible to gave 2 periods of LH surge?? Two periods of peak fertility.....

Thanks for sharing your results, Charlotte.  Typically a woman will have 1 LH surge per month.  We would expect an LH surge to last 1-2 days, then it will drop back down.  Having multiple surges per cycle isn't typical, but may be seen by women who have polycystic ovarian syndrome or who are experiencing menopausal symptoms.  

We'd love to talk through your questions.  Based on the name of the product you mentioned, we're guessing you may be located in the UK.  To contact our Clearblue UK team, please call 0800 917 2710, Monday through Friday from 7am-3pm.  Thanks!
