Am I a bad friend for not answering my best friend’s calls while sick and pregnant?

So my best friend (34F) started to argue with me (31F) for not taking her phone calls or answering her texts.

For context, I am 13 weeks pregnant, having a hard time with my pregnancy symptoms (vomiting, mild cramps, constipation etc) on top of having a chest infection.

So I was at work yesterday when my best friend, Amber called me - at work I’m not allowed to take phone calls unless it’s an emergency and Amber knows this. So when she rang I snuck off and answered…. This was the typical to vent about sh*t going on in her life but this one is where police have visited her house because of neighbours and landlords complaints of anti-social behaviour and smelling illegal substances.

The anti-social behaviour is her daughter being noisy playing out in the garden at 7.30pm (in the summer!) and Amber’s boyfriend smokes marijuana. So she was stressed that she will be kicked out of her home due to these complaints - I had to tell her I got go as I’m at work and don’t want to be caught.

So today I’m feeling awful, morning sickness, breathless with a headache, low energy and having to go to work. So I wanted to self care before work.

Amber rings me several times, I don’t answer. She then messages me asking “why are you being funny with me?”

Amber then tries to ring my boyfriend George who I live with, he doesn’t answer and she messages him asking the same question why I’m being funny with her.

George responds on my behalf “she’s not very well right now” and Amber kicks off saying to George “we’ll just because she’s in a mood she shouldn’t take it out on me who has been there for her”

Amber then messages me again pretty much having a go at me for not answering her phone calls and I need to “get my head out of my a*s and stop putting my moods on [her]” I just plain out not responded.

Am I being a bad friend?

Thanks for the unhelpful comments.
If you don’t want to read it then move on instead of making an unnecessary comment/statement.

I’m asking for clarification and help, that’s what the site is for.
