Not sure if my last question was posted but I'm going to ask again.
So i have 3 possible situations for this:
First is that i had protected sex on November 24, 2015 (7th day of my period). The situation is that when I was trying to put on the condom to my boyfriend I realized that it was on the wrong side so I flipped the condom and put it on my boyfriend. I'm worried that maybe that pre-cm got on the condom. Is that enough to cause pregnancy? Considering that we had sex on the 7th day of my period and I was still kind of spotting that time.
Second is that somewhere between November-December my boyfriend and I made out and after making out he ejaculated on my stomach. A few minutes after that, i stood up and wiped the semen off and took a shower afterwards. But while I was taking a shower, I wasn't touching my vagina, just my stomach just to wash off the remaining semen. I'm worried that maybe some of the semen got into/washed down to my vagina while I was taking a shower. Is that enough to cause pregnancy?
Third is that I've been travelling a lot this December (via bus), like on December 18-21,2015 i had 5-6 hours travel to a place and another 5-6 going back to my hometown; and on December 25,2015 i had a 2-3 hours travel to a place and another 2-3 going back to my hometown. It's been months since the last time I've traveled to far places. I've read that travelling can disrupt a woman's menstrual cycle.Could this be the possible reason why I'm spotting for the past days and not having like my actual period?
