Girlfriend Frequently urinating.. sign of pregnancy?

Look for more signs like unexplained nausea, headaches, feeling dizzy and light headed, tender breasts, (no period) and darkening of the skin right around the nipples on her breasts. I found out that im pregnant because my breasts were SOOO sore and i heard this could be an early sign. I hope i've helped. When its been two weeks, get her a test and tell her to take it in the morning the first time she gets up, This is when the HGC levels are very high and thats what the tests measure. If the test comes out negetive, wait about 2 weeks and take the test again. i hope i've helped
