No idea what to think 😢

At 11 DPO I got 4 positive pregnancy tests and then I tested the next morning (12 DPO) with a Clearblue Digital and got a positive. I tested today on the day of my expected period with a Digital Walgreens test and it came back negative but my period still hasn’t started and has no signs of coming. I also went online to read the reviews of these test and every review said they were bad tests, most of them said the woman wasn’t pregnant when she was or just never even worked in the first place. I just want to know if anyone else has had a similar situation but still ended up being pregnant and having a healthy baby?
