unplanned pregnancy and confusion

Leah Margaret • 3 children to adore, and adding one more! My fiancé Craig and I are expecting pink bows on 06/04! 🎀
This is going to be a confusing topic/post. This is my 4th child but it is my first pregnancy with my fiancé and his first child completely. We've been great friends for 10 years, JUST friends as I was with my ex Nick for 8 years and have 2 children with him. Anyways, Craig and I decided after Nick and I were apart for a year to try dating. Obviously things have been amazing as we are engaged. We lived with my mother from Feb of last year until mid-end July. I had been paying rent but stopping working after Craig and I started to date due to him being unhappy/not comfortable with the job I was working in. My mother was fine with this as I had paid more than double what was asked of me for months prior to him moving in. When the lease ended my mom ended up moving in with my brother and we enddd up moving into the inlaw suite at his parents house. We have both been unsuccessful at finding work currently. Craig has major mental health issues that make it almost impossible for him to work with other people. I have many years of experience in retail management which is both a good and bad thing (I will be told I'm "over qualified when looking at jobs under that position). I also have a domestic disburse record that makes it hard for me to work. Anyways, we had been talking about children and decided we wouldn't try to get pregnant but wouldn't prevent it. This was until his parents became increasingly upset that we weren't contributing anything outside of time, energy, chores, etc. Due to this we decided to go on birth control. Well one month into the pill I had two periods then found out shortly later that we were pregnant. Now I don't believe in abortion for myself, although I have no problem with others choices. So we decided to keep our baby girl (now I'm 19+2). We still haven't told his parents as we are terrified they will kick us out of our home, which makes me unable to actually enjoy my last pregnancy. I've become very depressed and upset over the situation although I understand where his parents would be coming from as outside of food we get for ourselves they support us. He is 34 and I am 30. I am at a loss though. Between emotions running high, pregnancy and other things we have been arguing a lot and some of the things he says hurt me. To go back a little, after my daughter was born August 2015 I did NOT have a period for 10 months, they thought I could be going through early menopause. Obviously they were wrong. Now I'm showing and having even harder times finding employment. I have applied for state assistance as well as SSI as I am technically disabled. The question here (outside of the rant) is what we ould be the best way to let them know? They have never liked me and think I am using their son for home, rides, money, and so on which is not true. I love my fiancé but should we get kicked out I know he will stay here and I will go to my mothers. (Again part of his mental illnesses). I'm just so unsure and confused. I want to be able to tell people about my pregnancy and not have to hide it. What would you do in this situation? (Btw he is looking for work even with the mental illnesses but has had no luck). Any input would be amazing.
