worried again!! second pregnancy

[glowworm00]

My last period started on 1st july and as i wasnt expecting or planning a pregnancy as i did last time, i dont know when i ovulated.
I had a strange feeling i may be pregnant so did these tests.
Are these strong enough for how many days i could possibly be?
Thanks

They are definitely positive even if though the lines aren't very dark. Just keep testing every couple of days and it should get darker.
