help!!!!

I have had 6 days of super positive opk's? didn't keep them all because it doesn't usually last this long the first 2 days I used clear blue digital and the last four I have been using the strips.i keep testing because my Dr told me to do it, this is the second month I am tracking it. I'm not sure what is going on? I have been ttc for just over a year now😢please tell me there is nothing wrong with me. my son is turning 6 and keeps asking me why he can't have a baby sister.
