CD 30 and positive OPK. Pregnant?

Its day 30 and I had a very clear positive OPK strip. I also had a positive on july 5th. I took OPK with first morning urine and then I took a cheap test and it was negative but wasn't FMU. Will retest in the AM but just curious whats going on?? Can LH surge right before period or is it a sign im pregnant?
