Emotional wreck anyone?

Probably just letting off some steam with this post...the first 12 weeks I was a nightmare so emotional, crying, bickering with my bf over the most silly things! Then second trimester hit and I felt great! Now at 31 weeks I'm back full circle and completely emotional again! My boyfriend is in the army gets home some weekends, was really looking forward to this weekend with him but I was so picky and feel like all we did was argue and me cry! I don't think I can cope with this again till baby arrives 😫 anyone else been feeling this way? I'm in need or so reassurance and sympathy 😭 x
