Opk progression. No more confusion!

Sedaya • My name is Sedaya and I'm 23. My husband and I have been together since 2009 and got married April 2015. We have a four year old daughter and had our second daughter 4-16-16 :)
So I took the last test just now after bding! It looks positive to me although I have no heavy cm. I hope there were some strong swimmers! What do you think ladies? Is the last one a +?
