Bubbles in pee?

I'll be 38 weeks on Friday and have noticed for the past 2-3 weeks that everytime I pee there are a lot of bubbles. I'm not urinating fast or a lot so it didn't make sense to me. I Googled it and read that it can mean there is lots of protein in the urine. I'm worried I have pre-eclampsia and will be talking to my ob about it today, but was wondering if anyone else this far along as noticed the same.

Update: I mentioned it to my OB at my appt and she said it is not indicative of pre-eclampsia so if anyone else has this and is worried, don't. She said anytime you eat high protein, like a big steak, you will urinate it out. Some protein in urine is expected because of diet.
