4 weeks 1 day

Today I would be 4 weeks 1 day pregnant. I had nausea, couldn’t smell certain foods, headache, pelvic pain, sore and painful boobs/nipples. I got a positive pregnancy test on Sunday (so 3 days ago) And last night I began spotting. Just light pink. I was hopeful that it would go away. Well it didn’t. It stayed light pink all day until right before supper. Went to the bathroom and there were big clots! Do you think that I’m experiencing a Chemical pregnancy? All of my symptoms went away this morning.
