Help..I’m so confused and don’t want to be heartbroken..

Lea

So I made a post Thursday. That I got a positive on a cheap pregnancy test and then went to the store to get a First response early response within 30 minutes and that came back negative. People told me that my pee was already too diluted and that’s why it came back negative and to try again in the morning.

That was from Thursday...

On Friday and this morning. I’ve right away tested when I got up and it has been negatives. At this point I’m 6/7ish days late for my period.

These were the test results from Friday and this morning

Could I still be pregnant or do you think that first one was a mistake? How does a chemical pregnancy work when it comes to taking tests? Could it have been that?

Thank you for your help..I just want this so bad and I’m so confused. I’m going to call my doctor but they don’t open again until Monday.
