Thinking I’m prego with baby number 2.

My fiancé and I aren’t getting married til 2020 so we decided not to use protection but we aren’t actively trying. We aren’t tracking when I’m ovulating and all the stuff to ttc. My period is always on point to the day for the past 6 months. This month I’m a week and a half late. I’ve had all the pms symptoms plus nausea. I’ve been moody more than I normally feel but I’ve also have a lot of stress in my life here lately. We have both been at edge. I’m not sure if he feels I’m keeping this a secret from him or not but I haven’t taken a test. Im not sure how I feel about if I am pregnant. We have a 4 year old and want more kids and was so excited when we stopped preventing (6 months) but now that it could be possible... I’m getting all nervous, scared, worried, hateful. Is this normal? I want this! I want this bigger family! But I’m getting angry thinking about being pregnant... WHY?!?!?!

I’m not one to open up to him and I tend to be angry rather than expressive and open.

Please help me make sense of why I’m angry and hateful rather than happy and excited. 🤯
