Feeling very emotional :/

This may be too much information for some on here.... But today me and my boyfriend had sex for the first time since after our daughter passed away last week as a stillborn. And as we have been for the past 2 years, he didn't wear protection and he came inside of me... (Sorry for the info)
But then later on in the day he texted me asking me if I should pick up plan B so I didn't get pregnant. I flipped out on him because after having unprotected sex for 2 years and carrying our daughter for 22 weeks, and knowing how upset I am of losing our child, how could he possibly say to take the pill to stop what could possibly be our next child?
And I freaking out for no reason or do I have a reason to be upset?
