Am I pregnant or not?

Hi everyone!

I have a 10 month old already. And my husband and I are starting for another baby. I took 3 pregnancy tests last week on December 16 and on the 17th, they came back positive. But I also have Covid( just found out yesterday) . I’m at a lost if I’m actually pregnant because a few days ago I went to a spot where you get tested for free ( pregnancy tests) and they said it was negative. They said it might have been to early to test since my last period was November 24th. With that being said I think I’m starting to get my period. So I’m at a lost. Any thoughts?

Edit: took another pregnancy test today. Came out positive. But looks like my period is arriving today. so I’m confused if I am pregnant or not.
