Ive had my birth control(Paragard) for a little over 2 years

Ive had my birth control(Paragard) for a little over 2 years. So once my Fiancé and I started to conceive I had my birth control removed on the 17th had sex on the 18th. My AF came 5 days late and lasted 5 days, afterwards I followed the Glow calendar for ovulation. We had sex everyday during ovulation for 3 days during my highest peak. I ended up taking 2 pregnancy tests they were both negative. Both two days apart, then today two days later I take a ClearBlue Digital today not even with first pee. But those seemed like the longest 3minutes ever! now I'm about 2weeks pregnant!!!!!! 😎😍😍😍👶👶🙈🙉🙈🙉🍼🍼🍼🍼🍼
