Have I ovulated yet?

So my husband and I are trying for our first baby :) I bought a maybe baby saliva ovulation tester and it suggested I ovulated around day 10 or 11. I thought that might have been a bit early but the ferns were intense so I guessed it must have been right. Yesterday, day 15, I bought some urine ovulation testers just to give them a go as well. I did one today, and a faint line came up in the test. I know this doesn't mean the test was positive, but could it mean that I am coming up to ovulation? I don't want to have been wrong last time, we worked so hard haha and to have to do that again right now isn't really do-able. Does anyone out there always have a faint line show no matter what time of the month? My last cycle was 30 days long, and that's the only real cycle I've had since coming off the pill. I guess no one knows for sure but I just want some reassurance that I ovulated on day 10 or 11 and that it's not actually about to happen in the next few days! Thanks :)
