Okay so this morning like the past 5 I’ve taken a pregnancy test to test out my trigger shot. I test in morning and afternoon. However this morning was pretty light still obvious positive but lighter. But this after it was darker than this morning. Has anyone else had this happen and it just be the trigger shot or is it a possibility that my body is actually producing hcg due to pregnancy???? I’m about 5-6 dpo and trigger. I ovulated same day as trigger confirmed by my dr.
