Positive home pregnancy test. Negative doctors test.

So I took 5 test between last Tuesday Morning & Wednesday night. All came back positive (some more faint then others) Friday I turned 4 weeks. Yesterday all day I had bleeding (normal red period blood) so today I got into see my doctor. There test came back negative. So they did a blood draw and will call me in the morning with results of my HCG. They are thinking it’s a Chemical pregnancy. Anybody had this & turns out your still pregnant? Or anybody had this? Tell me your stories. Trying to keep hopefully. (I have a almost 5 year old. Had a miscarriage 2 years ago next month. & a 11 month old)
