My girlfriend and I started having sex on october 15, 17 and 19. She missed her period on november, her previous periods were in october 3, and middle of september and late august and early july, her periods aren't very consistent, she has missed her june, may and april period. She has experienced backaches in early november and a little bit vomity. As of right now, shes worried that she has yeast infectino because there is a liquid that smells bad discharging from her vagina. I used a condom, and I believe I used it properly as I inspected it afterwards and it didn't break. I never actually ejaculated into her either but there was precum inside the condom when I pulled out. And we also went on a 11km walk in late october for fundraising. I was wondering what are the chances she coudl be pregnant. She has been pretty much normal lately except an increase in cravings, which may be due to her yeast infection. Anyhelp would be greatly appreciated!! Sorry to bug u guys on ehealth forum again! But this time I truly will stick to abstinence.
