No, your partner will not feel your pregnancy symptoms.
A yeast infection can be from a couple different things.
Here's some tips for prevention. Are you taking anything for your current yeast infection?
Are you new to the pill? If so, then starting and suddenly stopping could certinaly cause a slight imbalance. It usually takes around 3 months for your body to fully adjust. They can cause sore breasts and other pregnancy symptoms.
Are you sure you're not just sick? I mean, it seems more probable since your partner is going through the same thing right? Otherwise, just wait until you can take a pregnancy test, but you wouldn't be getting pregnancy symptoms AND negative tests-- that's just why I'm thinking its not pregnancy.
If these symptoms get any worse, speak with a doctor-- did you have a doctor check for your first yeast infection?
