I think I had a chemical pregnancy because I'm Coeliac 😔

Katie
My period was meant to be due on the 28/10 , by the 30th still no period so I took a test and saw a faint positive and I was so happy ! I took another test on the 31st I took another and another faint positive that was darker than the day before , I told my boyfriend and we were both so happy ❤️ 
The next day 01/11 I had a bit of spotting and I was worried , it started off light and pinky colour I thought it was just implantation bleeding I took another test and struggled to see another line as much but felt like I could still see it faintly but a lot fainter than before , the bleeding seemed to get a bit heavier and I was really starting to worry so I decided to go to the walk in centre the next day to see if they could help , they told me it was too early for a scan as I was only about 4 weeks they estimated but she did do a blood test to check my HCG levels and told me she'd get back to me in 24 hours , I am still awaiting my results.... Since yesterday evening the bleeding got a lot heavier and I experienced cramping, I took another 2 tests and they were both negative. This morning 3/11 I woke up and there was a lot of blood when I went for a wee I felt so much blood come or of me (sorry Tmi lol) I also saw what seemed to me a bit of a blood clot in my pad.. I am convinced I've had a chemical pregnancy even though I haven't received my blood results yet I'm really not feeling hopeful :( I've had coeliac disease for 2 years now , does anyone think this could be linked ? I feel so broken inside, I'm only 22 so I'm confused why this would happen to me if it has :(
