Yes it is possible, but it is also very rare.
well i would say there is always some left over blood like 3 days after..so i wouldnt worry.. also you could be having too rough of sex.. and you could have been really dry and made it raw.. so i still wouldnt worry.. just try to be easy.. cause you could have a lil sore.. or something..
Anything is possible. I just had my 5th baby on 6-13-07. I found out I was pregnant with her the first day of my missed period which is rare for me. I normally don't even test until I'm a week or 2 late. The only reason I tested that day was because I had been tracking my cycles very closely for about 8 or 9 months. Out of those several months, I had had all but 2 30 days cycles. So going by that, I was a day late. Anyway that morning I woke up and got to work. I started getting really sick. It wasn't from the pregnancy yet though. I was genuinely sick. I was running a fever also and almost had to go to the hospital for dehydration because I was so sick. Anyway, on my way home I stopped by Walgreens to get some Gatorade and I grabbed a cheap HPT. I wanted to take medicine and I wanted to test because I thought, what if on the off chance I was pregnant and taking medicine that I'm not sure is safe during pregnancy??? I get home, take the test and before I even had my pants buttoned, I had a big fat positive. I was shocked. The reason, I am giving you this long drawn out explanation is to tell you that I didn't expect to be pregnant at all. If I ovulated in the middle of my cyle like I normally do, I would not have been pregnant. I was even taking the ovulation predictor tests and they came out negative mid month. I ovulated early (which probably explains why I got such a quick postive). Sure enough, I had my baby 6 days early!!!! I had to have ovulated very shortly after my period, which is very rare; especially when you have longer cycles. You tend to ovulate mid month on; not before. Sorry so long!!! I just wanted to explain.
