Haven't ready through all the replies but as a father of 2 here's a few thoughts.
Not sure if anyone specifically addressed the part where you said you are pregnant out of wedlock and your fear of telling parents. I didn't have to go through this but have friends that did and depending on the parents the initial reaction may not be fun but most of them once they accept the reality of the situation will get over any anger they have and support you. I mean that child is going to be their grandkid and if they want to be a part of their life they will have to accept the situation and move on and love that child regardless. May make for some tense moments and time before the baby arrives but if you can get past that a new grandchild usually smooths things over with the parents at some point.
Like many others have said, this is no longer about you but the child and your partner. They come first over anything you have going on in your life. That's not to say some of us dad's here aren't guilty of putting ourselves first at times because we can't help it but the more you commit to what they have going on before anything you do, those times where you really want to do something for yourself become easier for your partner and kids to let you have over what they have going on. Kids are sponges so everything you say or do or the type of things you do in in their presence is going to have either a positive or negative impact as they grow. We aren't perfect and will make mistake but just be present and form a relationship with your kids. My 2 daughters are completely different personalities so it's an always changing thing with adapting to whatever they are going through or have going on. My oldest is 11 and feels like going on 16 already with the mood swings but at the end of the day even if she gets mad at me over something during the day - even if I did nothing wrong that caused it - we still hug and end the day on a good note at bed time.
As for your relationship with your partner, don't go to bed angry. Whatever it is you can always work it out and make an effort to get to a point before going to bed where you aren't angry and have a plan to talk/work out whatever is the source of it. I also have a "let's not start the day off on a bad note" rule with my wife as there are times where she may snap at me first thing in the morning over something stupid and then I leave for work in a bad mood and it sometimes affect my day. I've done it myself as well so I'm not 100% innocent but I've had mornings where I didn't even get in the shower yet and my wife dropped a 4 letter word at me or in regards to something that was going on at the moment that apparently frustrated her which I usually respond with something like "what a great way to start the day, good morning to you too I love you!" That doesn't exactly go over well either but once things settle down I usually get an apology. You are going to have fights over stupid things and that is normal. You work through it no matter if its a big or small thing. A couple that doesn't fight probably has other issues going on and not communicating and keeping it bottled up usually never ends well.
