Can OPKs detect pregnancy?

Zarah • Professional Photographer in Arizona. Married for 4 years Currently Pregnant with peanut #3
So I had a miscarriage over a month ago, I've been taking OPKs to see where my cycle is at, I had 1 negative and then 7 positive in a row. I've never had that many in a row before, so I'm thinking either it's still picking up on my hormones from my miscarriage, orrrrr I'm magically pregnant again. I've been kinda avoiding taking a prego test, because I don't know if I can trust it. What do ya'll ladies think?
