Do you think this is the start of a chemical?

Hi I don't know if I'm being paranoid or not but got my BFP yesterday (not with morning wee) and did another this morning with FMU thinking the line would be stronger but it's definitely fainter (bottom one in the pic is today's)
I don't know if I'm worrying myself over nothing but surely it should be darker today and not lighter? I'm going to buy some more tests later for this week.
Has anyone had a lighter line like this and gone on to have a successful pregnancy? I know only time will tell really but the days just go by so slowly when waiting for these things.
Thanks

Ah I see no need to worry. It's only one day in between and you have such a clear positive.

It's likely that you just had more to drink the night before the most recent test or there's a slight difference in the sensitivity of the tests.

Relax.

Thanks. Don't think I will relax properly until I've seen it on a scan!
