Sad my dad died and will miss my pregnacy

So last month my dad died suddenly because he apparnely had a heart problem his doctor never looked for. So after loosing him I found out I was pregnant I have one child and he was their for everything with her. Im 7weeks and I feel so emtional. I was in the store the day before yesterday and saw a old guy that reminded me of him I started crying. It was horrible it just makes me sad that my dad wont be around anymore I wake up and go to call him and just wanna hear him say some smart ass shit or tell me he loves me. Its hard that I never got to say bye. The hormones have just made me feel worst about it
