I’m so confused 😪 am I pregnant or not?

I miscarried May 8th this year. The miscarriage ended May 16th. It is not 5 weeks today since the bleeding has stopped. I have yet to get my period and I am 4 days late on it and I am having all sorts of symptoms. My breasts are sore AF, I’m having cramps, my back hurts so bad sometimes it keeps me up at night, I sometimes get dizzy or have small headaches, and I crave apple juice. I feel all the pregnancy symptoms I felt before. BUT I’ve take a bunch of tests and they’re all negative. EXCEPT 2 days ago I took 2 tests and looked at them 5 or so hours later and they had a faint but visible line... ?!?! I’m so confused what does this mean?!?! I went to the hospital today for all these symptoms and they took my blood but I have yet to get a call back.. maybe that’s a good sign I’m not sure?! I hope I’m pregnant again I really want a baby so bad!! But I’m also scared shitless..... I don’t want to lose it again. Please help me out; has anyone else been through this???
