Had miscarriage in march. Chemical in June. Pregnant again... but

Ca

I'm pregnant again. Have really DARK lines.

Worried for chemical. What's interesting though is i took a test bc I was feeling symptoms but period isn't due for two weeks and app says in my just now ovulating

Possible I got pregnant last month? And my period was just spotting?

I feel lines shouldn't be this dark if period isn't due for two weeks
