This is weird

OK last week glow said I was ovulating on the dates 27th-1th. Then on Wednesday I tested and it showed two lines which mean ovulating . so I took another one Friday and it was two lines but the one line was very faint. Oh I when I updated glow on Wednesday saying I took a test and it said I was ovulating it change my dates to me ovulating on the 24th-30th which I think crazy. So last night I was just bored and had an extra test (ovulation) so I took it and it show two lines and showed up right away and was real bright. So I just don't understand cause I can't still be ovulating has anyone had this happen before.
