Hello. I joined this site to ask a question I cannot find an answer for. So, this is my situation. I had unprotected sex the last day of my period (10.6) and my period was late 10 days (this happens to me twice a year and my period always shifts from 6th to 16th of the month) so this was not something unusual, plus I have recently moved to a new house and I have a completely new routine so that could have been the reason as well. When I got my period it was heavy and painful (as it always is) so that was good. Then I had protected sex (condoms) with my husband a few times after my period was over. Another info, we were on a trip and I was exposed to a completely different climate + I have been under a lot of stress since moving. Thing is, my breasts have started to hurt 10 days after the last day of my last period, and they have continued to hurt up to now (pain is mostly concentrated on the outer sides of my breasts) and my nipples are not overly sensitive. Another thing is, I have noticed a change in my discharge which became sort of thick and had a bit of pink in it (more like brown/pink but very translucent). I took a pregnancy test yesterday and it was negative. 

Finally, the question is... Should I, and when can I take a new pregnancy test to be sure if I am pregnant? Also, is there a possibility that my current condition was caused by stress and change in environment?

Hoping for an answer :)
