Chemical Advice

So I had a positive HPT 3 times in the last 2 days (13 and 14 dpo). Period [was] 2 days late. Negative test today (15 dpo), period/bleeding just started. I’m assuming this is a Chemical...?

Periods don’t give me major cramps. I have cramping but it never ruins my day. But omg...this cramping isn’t light. It’s pretty that typical for a Chemical??

Thanks for any comments or advice! Pretty sad right now :(
