Trying to conceive. I had unprotected sex during ovulation now am having whitish thick discharge could it be pregnancy? My period will be in 10 days.

Might be a yeast infection. There are several causes of thick white discharge and most of them have nothing to do with pregnancy. A lot of women notice a change in their discharge during pregnancy, but at this point it is too early for this to happen

At this point your best indicator for pregnancy is a missed period, and missed by about two weeks. As you probably know a woman's cycle can be irregular for no other reason then it is nice outside. Which is to say if you miss your period by a day or two it isn't really missed but late, but if you miss your period by two weeks then something is up. As well most over the counter pregnancy tests test for a hormone level that is consistent with your period being missed for two weeks. So the news is that you're going to need to wait for more then three weeks before you know for sure. This is why getting pregnant can be painful sometimes because you notice little things that could be a sign of being pregnant and it comes that it is in fact not.

Good luck and enjoy the baby making process because it'll all change afterwards!

I will agree, this should not be anything to do with pregnancy.

I will ask, how you are testing for ovulation times. Most online and phone apps are not correct for everyone. You should be medically testing, if you are not already.
