If you have missed your period, i would advice you to go for a home pregnancy
test, as you could be pregnant. Sometimes there is increased watery discharge if you are pregnant.
If the test is negative, you need to go for a gynec check up to rule out local infection and a few tests after consulting your doctor as if you both are trying since a year then you need to go for a few tests to rule out and cause for infertility
either in you or your guy.
Don't worry, take care, All the Best.
