Confused & Stressed Out

Ok little backstory to make it make sense. I was 7 days late for my period. I was extremely tired, had spouts of dizziness and nausea was constantly getting up to go to the toilet literally every night and I thought I had diabetes because I had been craving a lot of sweet things and literally stuffing my face with anything sugary anyways I decided to take a test on the off chance I was pregnant anyways it came out positive took another test 2 days after and same thing and another a few more days later and that also came out positive. A few hours after the last positive I began to bleed bright red blood and my period came heavy and with full force anyways horrible painful cramps so I just thought more time it’s a chemical pregnancy and that was that. My period this month has been nothing but strange the first and second day we’re normal for me heavy with cramps but I had a lot of clots in my pad the third and fourth day we’re not normal I was still very heavily bleeding but it had changed from bright red to dark red blood with no clots I had spouts of dizziness and nausea. TODAY is day 5 on my period the blood is brownish/pinkish which is strange and it’s been heavier than my normal day 5 cycle & I’ve been so so so nauseous and so dizzy it’s not even a joke, day 4 & 5 I’ve had a pulling cramping sensation in my lower stomach I’ve had lower backache and I’m just so tired it’s like I’m starting my period all over again?? Could it just be that my body is regulating itself after the cp or that I could still be pregnant??
