I am on CD10 and believe i just had ovulation bleeding(small amount of pinkish in my cm when I went to the bath room twice starting at 11.30am.) Unfortunally I work at 12 hour shift today and couldnt do an opk and wont get home till 6.30pm to try to BD with my husband. Could it be too late by then?? And if it is or isnt is the ovulation bleeding should I even keep testing with opks, will it just be over then?
