I think I’m having a chemical. 😔

I got all these positives and I was so happy because we have been trying for a year and half with all negatives up until this point.... today I started bleeding and at first it was just a little brown spot when I went to the bathroom, but now it’s bright red spotting, enough for a liner.... I really hope it’s not a chemical but I probably just have wishful thinking... I didn’t even have a chance to go get bloods done... 😭😭 (top test is today’s...)
