Chemical?

Cheyenne

I have a question. I was a day late on my period never took a test or anything but was having like a few symptoms of pregnancy the next day after my what was suppose to be the start of my period i was bleeding way more than i normally would on my first day like i had to change my pads and tampons way more than i normally had to on the first day and everytime i changed them i noticed really big clots on the tampon which noted i have never had that happen before so i did some research and saw that i could be having a chemical pregnancy. Is this true i would really like to know before i try to go to the doctors. Also to note i stopped having symptoms once i started bleeding.
