STORYTIME-NEED OPINIONS

I'll try to be quick and to the point. Just roll with me ladies. Some of you have seen my pics,here's the situation. Felt pregnant. Appetite picked up and breast were tender. Af was due Monday and I tested. Walgreens brand worked for me and was a faint positive. A few hours later I confirmed with frer(2nd pic). Wednesday I started spotting out the blue. Retested and got darker lines(3rd pic). Bleeding picked up so I went to urgent care,after all I have a positive digital. They informed me that their urine test was negative eventhough by my test pics taken a couple hours later they thought I was. I asked for a blood test and they refused. Thursday I bled heavily. Friday not so much and only spotting since last night. My symptoms have increased. Can't touch my breast,bumps all over my face,my body itches,I threw up yesterday. My question is could it have been a chemical? Should I retest and if so when? The lines should be fainter right? I know a lot of you have experienced this. Also let me say I have experienced bleeding throughout all my pregnancies but never as heavy,yet the bleeding didnt last long enough to be my period.
