Need real help!

So I was ovulating on the 15th and 16th the husband and I had sex on the 13th-16th I took 2 blue dye test around a week later and got positive lines and then took a red dye test and digital and said negative so I thought those were evap lines I just took a pink dye test today (2 weeks now) and saw an extremely faint positive and my period is due this coming Sunday the 30th! Could this mean I really am pregnant or could be another evap line? You can not see the line unless I put it up to a light or REALLY look at it 🤦🏻‍♀️ 🤷🏻‍♀️ just needs some insight!
