Positive OPK 7 days! Help?!

Michalle

So since Friday i have had clear as day positive OPKs. Bd’d a lot! And today i was cramping some on my right lower abdomen so just decided to take another ovulation test and it was very positive still! Took a pregnancy test and it’s negative. Could i be testing too early? I read that OPKs can pick up early hcg before pts. Please help if anyone has had this happen to them.
