I am now 30 weeks pregnant and in the past 3 weeks it's like a switch has flicked. I feel so uptight and worried about everything and anything. Waking early in the mornings and tired all day. My pregnancy wasn't planned and although my partner and I are settled and buying a home , I feel there has been some judgement as we are not married. I haven't worried about this since first trimester and now it has all flared back up! Has anyone else experienced mood changes like this ?
