Accurate Pregnancy Tests?

My husband and I have been trying for 3 months for our second baby. I decided this month to get serious about ovulation tracking. I started the day after I stopped my period (first day last period was January 22, last day January 27.) We had sex the 28th and yesterday, the 31st. Today, I got 2 positive test results. I’m so confused. I just had a period less than a week ago and now I have two positives. Is this accurate? Is there a chance that I’ve either miscarried or am having a chemical pregnancy? I’m worried. The pregnancy tests are two different brands.
