I'm heartbroken :( tmi

We have been ttc for 2 months and yesterday I was at 12dpo so I took a pregnancy test and got a bfp. We were over joyed, I cried and couldn't wait to tell my mom. Well 3 hours later at work I felt what I thought was super watery cm (which I have had before and mistaken for a period). I went to the bathroom and there was blood soaking my panties. I was heartbroken. I only had tampons on hand so I put one in. Later when I went to take it out it had brown blood as well as dark red and red tissue (when I'm on my period I have black blood clots). The blood did not soak the tampon and it did stop. I went home and took a test and it was still positive but I new It was a chemical pregnancy. I cried a lot. Then took a test this morning and it was a bfn. Idk what to do. I'm so so sad. Now I have to wait for my period and try again 😓
