In need of emotional advice

Rebecca
So, this I our first pregnancy and it is really affecting me emotionally. I'm almost 12 weeks and I am very moody, irritable, and just want to be alone a lot of the time. My husband has noticed that I'm different and "just not myself". He's very empathetic- so it really affects him too. 
Most of our friends drink on the weekends and I just don't want to be around them. Pre-pregnancy I used to drink wine every night to "take the edge off", and I'd go out w friends or we'd have them over on weekends to hang out and have some drinks. Now that I can't drink I just want to stay at home by myself. My hubs is starting to feel pretty bummed out too and I'm worried it will affect our relationship. 
Has anyone else experienced this? Will this go away - or what should I do?
