ovulation really early

Carolina
Hello ladies. Back story stopped BC nov 29th had a period December 25th. Had sex the 28th or 29th, can't remember. Had sex again the January 1st and yesterday. Today I get a positive on ovulation. Ovulation wasn't till the 8th. Anyone ever have a positive this early? Mine have always been consistent. So this is new, lol. Comments appreciated. I think we may skip sex tonight seeing we've done it 2 days in a row and do it following day...
