OPK Question

Jaclyn
Top test is from last Friday (8/7) and bottom test is Sunday (8/9). We were on vacation so I wasn't as crazy about testing as I usually am. Is it possible that I could have had a positive test on Saturday as well? We bd'd on Sunday morning before I took the test and didn't get a chance to dtd again as we were traveling on Monday and Tuesday. Luckily we had a very active week up until then. Really hoping it's finally our month.
