I'm currently 4dpo but kind of confused I could possibly be 3dpo. My apps all told me I would ovulate on the 18. I got a solid Smiley on clear blue on the 17th. Which was our peak. We inseminated the 14th-16th-17th and the 18th but when I took another opk on the 19 it was still positive . On the 18th I felt ovulation cramps but I also felt them on the 19th as well. Do you think I should have inseminated on the 19 as well or am I overthinking things?
