Faint lines on ovulation tests going on 5 days

Jamie • I`m 32, been TTC for 2 years.
I have had constant ovulation tests for 5 days now, but negative pregnancy test (started cycle on July 4, should start new cycle on Aug 3 in 4 days). The line is faint, not as dark as the test line, but they are there. I am wondering is these ovulation tests always have a faint line during most of the month, except when it's dark for ovulation (I haven't taken them in a long time until now so I don't remember), or if it's an early sign of pregnancy. I would normally wait for a dr apply but Ive had miscarriages before and want to know if I'm pregnant ASAP before I lose it again. Dr won't give me a text until my period is late.
