Do i have a right to be annoyed?

Ok, so let me start off with the backstory, i had a miscarriage about 9 weeks ago now & literally got pregnant straight away, by only one time of having sex, we didnt do it anymore after that one time because my body was drained, i am now 7 weeks pregnant, i only found out a week ago & since i havent known what to do, now i understand there are lots of women on here who are trying so hard to have a baby so please dont take any offence, i am only 18, i didnt expect to get pregnant that soon again, we didnt try, it was unplanned and i am mortified. I dont feel ready in the slightest & please dont tell me i shouldnt of been having sex because i knew the consequences, in which yes in a way it is partly my fault.

But i told my boyfriend how ive been feeling, and i feel so horrible for the feelings ive felt, like confused, should i keep it? You know, the questions a lot of people ask themselves, my boyfriend told his mum about my feelings and she basically told me i shouldnt be having sex if i didnt want a baby, which is unfair, because it takes two to make one, she then proceeds to tell me that i will regret it if i plan to get an abortion, in which i have a big heart and i already know if thats what i chose id regret it for the rest of my life. The thing is i never said that i AM getting an abortion, i just feel confused and unhappy about the situation.

My boyfriend since has been arguing and making me feel like absolute shit by calling me a baby killer, telling me to grow up and that its my fault and should deal with the consequences. Thats whats annoyed me, we sorted it out he told me he didnt mean any of it and that its my choice but it doesnt take back what he said. Today he has been acting off, declining my calls, and then decided to call me back, im on the phone for half an hour and he doesnt speak a word, so i ask him whats wrong and he denies that anything is wrong, so i asked why he was so quiet as usually hes bouncing with energy, he then tells me that hes quiet because hes thinking about things, so obviously im trying my hardest to be there for him and he just doesnt have any of it, he then puts the phone down on me. I then called him back and he lies to me saying i shouted at him when i never, and just then turns his phone off, im just so confused, angry and upset and i have no one to speak to at all.. sorry its so long.
