15 weeks pregnant - so stressed and angry/irritated

[WhereTheresHope4]

I'm feeling so stressed.
I'm delighted to be pregnant (15 weeks). We've been trying for years through having fertility treatment and IVF.
But I'm just so stressed. My patience is zero.

It's so unlike me. Normally I'm pretty calm, chilled etc but lately I go from 0-10 immediately when something pisses me off.

I'm full of a cold this week too.
Today I was looking forward to finishing work early and chilling out. But a colleague wound me up big time and I can't stop thinking about it and getting worked up.
Then someone else said something which annoyed me.
My dog has been stressing me out (he's been acting different since I've been pregnant).
I just hate feeling this annoyed all the time. I'm worried about it effecting the baby.
And I'm sure I'm pissing DP off.
I don't know what to do.
I was cooking tea tonight and just burst into tears because I feel so out of control.

I am 33 weeks and it has NOT been what I expected.
My emotions were a hot mess all the way through and I have had pregnancy insomnia and a lot of anxiety/ out of control/ worry about the future type feelings.

At points I scared myself and my DH - I was hysterical at points and threw things more than once in rage during 2nd trimester.

My second trimester was much better (although I still woke my DH at 3am on workdays to sob uncontrollably for 20 mins before falling sound asleep leaving him bewildered and wide awake ) and third has been the best.
Everything is such calmer now.

I'm currently 26 weeks and around weeks 14-19 I was a hot mess emotionally.
My fuse became not existent and I was very angry and upset over everything and nothing.

Deep breaths, try to do things that are relaxing- I enjoyed reading in the bath sometimes but just take it a day at a time and it will likely pass xx

Thank you for your replies. Glad to hear I'm not alone in it! These hormones must create so much internal chaos!
Also I thought I was full of a cold which is what I said in my OP. However I've just done another LFT and it's come back positive. I really hope the baby is ok.
