Positive test after period?

So my period came on early two days early, normal period. But it only last 4 day but two days spotting and 2 days regular flow. Today something mad me nauseous so I took a pregnancy today. This is a rapid results first response. Both line are pink and showed up instantly

******UPDATE*****

I took another test this morning the line was a tab bit brighter. I didn’t even have to invert it my mother even saw the line. I called my doctor told them I wanted blood work they wouldn’t call me back. They are 45 mins away but there’s another location where I can get blood work. So I called my regular doctors office. They fit me in for testing all they did was a pee test it was negative this was around 12pm and told me there probably wasn’t a line there just me starting at the test and making a line show. They aren’t going to do blood work at all. Told me I can come back next month for another urine test but not blood work. *I had a miscarriage back in Feb* my doctors nurse emails me and said since I had a period there no way I could be pregnant it takes 14 days after a period to ovulate and that there is something wrong with my at home tests. I won’t be going back to them.
