Relationship problems

I'm having problem in my relationship atm I don't want to get into it really . I'm 21 weeks pregnant and 3 days and I shouted really loud today at my OH we had a big argument and I was screaming and shouting as I was angry cause I'm just so SICK OF BEING ALONG during this pregnancy , I love this baby with all my heart feeling him kicking me every day is what makes me happy I dunno what I would so without him now . I'm afraid I'm after hurting baby by shouting? I don't want any rude comments I'm in a difficult time in my life I just need some advice maybe some of you had bad arguments while pregnant and your baby was born healthy? I'm so upset just love my little boy so much
