2 months and never told my boyfriend

so my boyfriend and i had drunk sex one night back in November the same night he cheated on me with my “best friend” so him and i broke it off completely for a month then both realized we love each other too much to be apart and i totally ditched that so called friend... anyways within that month him and i were separate i hadn’t had sex with anyone else but started getting morning sickness and never got my period so i took a test and found out i’m pregnant i also went to the doctors and they confirmed it. the guy and i are back together now for almost a month but i’m so petrified to tell him that he’s gonna be a dad. i obviously know i have to tell him and yes i do want to keep the baby whether he’s game or not but i have INSANELY bad anxiety how should i tell him that i’m 2 months pregnant?! i’ve had every intention on telling him in the past i’m just so afraid of his reaction and how things will work out that it has forced me into fear and not being capable of telling him. i even had a bonfire at my house not long ago to tell him in private one on one but with my friends there just for support, motivation, and if all else goes wrong comfort, but even then i got so nervous i ended up running into the house to throw up and cry for a few minutes by myself. he did come in to check on me but i couldn’t tell him the truth i really tried but instead all that came out was “i just feel lightheaded”. can you guys please help me figure out a good way to tell him because he needs to know and he deserves to know and i love him and want him to be a part of our child’s life but i feel like my anxiety and fear has been building up more and more like the time i mean 2 months? i should’ve told him when i found out even though i wasn’t back together with him then i should’ve told him.

ADD ON:

lmao i’m an idiot for ditching the “best friend” that openly admitted to me that she lied to him to make him believe i cheated on him and took advantage of him being drunk and that she never liked me just wanted my boyfriend then had sex with him and broke up my relationship where a suicidal girl was actually happy for the first time in forever thanks to the one guy... so yea if you call that a friend and still think i should’ve stayed friends with her and left him then yea call me an idiot but i seriously doubt you would stay friends with someone like that😊ps don’t need people to be rude save the time and energy that goes into those comments i just wanted a little help not disrespect from a complete outsider.
