I’m so confused

Please help me. I’ve taken 3 tests at home, my first at like 8-9 dpo and it was negative. I have taken two since, and they were both positive (or so I thought). This is my most recent.

I know it’s faint, is it also negative? It was taken within time frame and everything .. I’m not sure, but I feel SO lost.. the clinic I went to also did a urine test, and they told me because I’m not yet 4 weeks that it may just be too soon, but I don’t get it? Were the tests I took false positives? My period was due yesterday- I have had no blood/spotting/ sign of AF at all.

But I have been tired and my boobs are swollen and painful. What’s going on? I scheduled another visit at the clinic on Monday, since it will have been over 4 week at that point they said they would most likely see a positive by then if I am pregnant..am I going crazy ?

This is my first time doing any of this so I’m very confused and feel a bit lost at this point. What do I do? Help me.
