I was having sex with my boyfriend up until July 3rd we broke up and I started having sex with another guy from July 6th on... I don't know what my lpm or lmp is let aline what it means I'm trying to figure out who is the father for the sack of me and my baby's safety because my boyfriend told me if its not mine I will get hurt so I need to know if I'm staying or if I have to run for the safety of my baby and I. My due date is April 1st.

With dates so close it's impossible to say who the father is without a DNA test.

If there are issues surrounding the paternity then you will need to conduct a DNA test.
This is safest AFTER the birth of your child.

From the information given it is impossible to tell who the father could be..

My lmp was June 25

You had sex with two men in the same week. Those dates are too close together to determine paternity without a DNA test.
