I'm 6 months pregnant and my boyfriend and I have been having sex ever since I found out I was and he cums inside me all the time can my body store the ?" Like we have sex every weekend and usually when I go to the bathroom there is green stuff on my underwear and little spots that are also green but look like rice

Your body store ? Store what ?

It sounds like you may have some type of infection, you need to see your doctor about this and discuss with him.

There is no reason a healthy couple, can not have sex during pregnancy, but should always consult their doctor

Your question is not very clear at all but from what I gather, you need to see a doctor. There should be no green rice in your underwear.
