Breastfeeding and 33 weeks pregnant

So I still currently breastfeed my 2 year old daughter which isn't a problem is usually twice s day unless she's ill or teething then it can be all day as she wants comfort.

I recently though I would check to see if I'm still producing milk or not or was she just using the nips without the milk which I am still producing but I'm unsure weather it's the milk now or colostrum as it's not as white anymore it's gone to a pail colour and is more that sticky textur.

I was told at the begging of this pregnancy that it's okay to breastfeed while pregnant but I just want to know if anyone else did it as I'm worried that she may take all the colostrum from the new born as that's the best part for any baby to get.
