Very very light pink discharge

Deana

I’m 28 weeks pregnant pass 10 days I’ve had loads more discharge sorry tmi but pass two days I’ve had very very light pink discharge only when I wipe. On Wednesday I lost my mucus plug big blob snot like with red streaks in it. But after posting on here I didn’t worry as told it can regenerate. But now pass two days I’ve had pretty bad lower back pain and period type pains not unbearable though.

On Friday I had horrendous sickness all day and yesterday one lot of diarrhoea but I don’t feel like I have a bug, do u think this is normal for third trimester??
