Te thing is it's not just a trickle, I know what you mean about every few minutes or just going and having to go again but it's really like a full bladder then I empty then 15-30 min later I gotta go again..
After 34 weeks, I lived on the toilet. It was so annoying cause I really felt like I had to pee and would go and only trickles would come out. Lol its totally normal
As the baby gr o wd the bladder has less space to expand. So it may not be full at every use.
Lol.. I'm 30 weeks and I go about every 15-20 min. Honestly about an hour ago I used the restroom got up walked to the bathroom door and had to go again.. it's a joke at my house lol
