TMI post: 36 weeks. Loose stools and upset tummy

Im 36 weeks pregnant with my first baby on Wednesday and so far no major issues except for my bowel movements and an upset stomach?

No extra discharge or change in anything else except for this. I’m taking my prenatals that ive been taking throughout pregnancy and im also on strong iron supplements as im anaemic.

Ive been taking these for months and normally my stools have been hard and i’ve been more constipated due to the iron tablets but the last week or so i’ve been having really really loose and watery stools.

Every time i need to go to the bathroom my stomach feels really upset and i get that yucky feeling.

Covid has been spreading about lately around my area so ive been isolating for a while so havent been around anyone to catch a bug and i havent changed my diet and even though this isnt really symptoms of it, i have been taking covid tests - all negative.

Is it possibly a sign of labour coming? I feel as though im too early for this?

I have been getting braxton hicks for the last few weeks but they arent painful, just a feeling of tightening.

I have also been getting a lot of pressure down there but again thats normal for how far along i am, baby is head down as well and has been since 31 weeks.

I have a midwife appointment on Wednesday so im definitely going to bring it up to her and see what she says but in the meantime has anymore else had these issues? Anyone know why this is?
