Bubbles In urine (Not Foam) Pregnancy.

She was pregnant before 3 months. Which was missed Abortion (Baby was not growing). That's why doctor prescribed Abortion pills for her. After those pills, everything is fine and she is in prescription of Torchnil and Folic Acid. She is saying that whenever she go to bathroom, she see some bubbles in she's urine. that's not like a foam, but bubbles with size of half centimeters as she said. Not so many, but noticeable. It can because of force of urine and bathroom floor I'm not sure. She said when She Urinate on Indian Toilet seat, there everything was fine. she only get bubbles in floor. She noticing that from she's pregnancy. but at that time, a urine test was also done with normal results. She don't know she has bubbles or not before pregnancy.
