Is this a positive pregnancy test?

Took this yesterday but didn’t notice a line till today since my bathroom is dark. Maybe evaporation line? However it is pink and not grey? Has this happened to anyone else? Oh also I am 5 days late but sometimes I’m irregular. I took two other tests and they came out negative. Also the other old pregnancy tests I took are negative with NO evaporation line, so that’s a little weird. I have been trying to conceive for over a year now .
