2 positive ovulation tests this month?

im new to using these, so the first batch i got were first response. some people recommended clear blue so i got that as well. both tests came back positive last week. we baby danced and all for 2 days. today, just for fun really, i tried another first response test and it was positive! and i mean, it was an obvious positive too, super dark test line. is this normal for some women or am i missing something? i have heard that a opk can show positive if ur pregnant, but wouldnt 1 week be too soon? just need a few opinions, thanks!
