Body playing tricks on me!

Nina
I felt so good about this month. I work evenings so it's hard to find time to bd with my husband. But I got a positive ovulation test on my day off and was so excited that we actually got to bd. I got my positive on 1/19 and had ewcm the 18th,19th, and 20th. Then today on the 22nd I have ewcm again. So did I ovulate this late and not the first time?! So discouraged and frustrated.
