Hi
I am on cycle day 21 and have 28 day cycles , I am pretty sure I ovulated on day 15/16 as had positive opk for 2 days along with the normal ovulation symptoms. Today I decided to do a opk test because I am quite new to using them to see how it would look when negative but it was positive! Photo attached. What could this mean? I had negative tests from day 17.
Any explanations about what you think could be going on would be great. Thankyou
