if her juices are extra creamy and white the she is proubly passing an egg that is at her peak of getting prego"ovulation time" if it is natually clear then you should have no prob...
ask your self or look at your sperm and look at her juices and see if you can tell a difference but a little tip ask her what was the 1st day of her last period then count 13 day through 18 day from 13 between day 18 is mostly the highest peak when she is ovulating and if she is in touch with her body and has normal periods then she would know from the different discharge. dont get me wrong you can get prego at any time but and by a drop of sperm so that scale can help you practice a little safer. also i would advise you to NOT rub you penis on vagina BEFORE putting a condom on because most men when their arroused they "leak" pre ejaculate and dont even know it half the time and that one drop is all it takes just ask my husband!!! we have 3 beautiful children! 2nd child from pre-ejacualation...with a condom after.... 3rd child off the yaz pill with no condom and a pull out and pill were taken properly for 3 months...(my husband has strong sperm,i have been prego 5 time from my husband) but every women and man are different, just be cautious! a note on the 72 hour pill does not always work a friend of mine who was a rape victum had took teh paln -b in the hospital and 7 month later found out she was prego...krazy yea thats what i said turned out to be the guy who was in jail baby who was her visiting from out of state dates and everything matched up to the date of the rape . (UNBELIEVEABLE) so in detail every persons body is different .
RE: White substance
It could be a few things:
- If you slip in a little before you put the condom on, it could be from you. This is probably unlikely - precum tends to be colorless, I believe.
- If you use a lubricant, or the condom is lubricated, it could be that. But again, this is probably unlikely if the lubricant is clear.
- Probably the most likely thing is that it was normal cervical mucus produced by your girlfriend as part of her menstrual cycle. This site: http://www.fertilityfriend.com/HelpCenter/FFBook/ff_fertility_signs.html has a description of some of the times of mucus a woman will have at different times in her cycle. Some (the stuff that looks like egg white, or is clear and slippery) indicates she is about to produce an egg which could be fertilized (high risk of pregnancy). Other (tacky, sticky, creamy) indicates she is unlikely to be fertile at the time you see it. Be aware that the site is targeted at couples who want to make a baby (the rules for avoiding pregnancy are a bit different).
This site: http://www.beautifulcervix.com/cervix-photo-galleries/photos-of-cervix/ has pictures of a woman's cervix over the month. It's a bit gory, tbh, but maybe informative if you want to compare what you have seen.
Note that Plan-B is most effective up to 72 hrs after unprotected sex/contraceptive mishap. So if you've passed that time, you may just have to wait it out if you think it could be from you.
Good luck!
