had a terrible first trimester with sickness and exhaustion but felt ok mood wise no sickness now feel faint sometimes which I'm getting bloods done tomorrow incase I'm low on iron but now I'm in the second trimester my mood is terrible with my partner I snap all the time then feel so.guilty he said he feels he can't do anything right. I say every day I won't be like that then I do anyone else experience this I was fine in my other 2 pregnancies so it's so out of character for me and advice welcome
