Whose the father?

I know it sounds terrible.. but I haven't gotten a paternity test done yet and I know I need to. My last period was March 5-10 2020.. regular 28 days.

I had sex with guy 1 march 14 & 15, we didn't use protection. I had sex with guy 2 march 21 & 23, no protection.

On April 2 I took a test and was negative. On April 6 I took a test and said positive.

I went in around 5 weeks and they measured the sac and said that it was more than likely guy #2. Also my original due date by period was 12/10. And they said by ultrasound 12/12.

Anyways since having the baby, the baby has dark blue eyes currently (11 weeks). Guy 1 has blue eyes and guy 2 has hazel eyes, his sometimes looked blue sometimes green sometimes lighty brown/ gold. I have brown.

I'm curious on who the father could be? Besides doing a paternity test.
