what spesific questions are you asking, your kinda all over the place there
if your asking whos baby it is, no one can tell you that, especially considering there was only a week inbetween the two, why do people not think of the consequeneces and just keep it in their pants or only be with one person at a time at least, especially a fetile time (sorry that wasnt directed at you, just in general, there are too many people who sleep with more then one person without thinking of the consequences)
if your asking for predictions, it really could go both ways (this is all based on a 28 day cycle, if your cycles are not regualr or not 28 days that would affect the calculations) your ovulation date is about the 20th (according to my math) sperm can survive for up to 5 days, but thats a long shot, so if thats the case it may be your bofriends....an egg can survive for 2 days (i beleive) so if you ovulated a or 2 late then it could be your ex boyfriends
the only way to be sure is to have a dna test after the baby is born
now if your asking about a bladder infection and uti, it is possible to pass it to them, but it wont always happen, males get bladder infections and utis much less then women, expecially if they are cercumsized because there is nothing to keep the germs there
