💜Early Symptoms of Pregnancy?💜

So. We've been trying for another. And no luck yet. However, we've been at it about every day to every other day the past month. AF is expected to arrive in 3 days and I have no symptoms of it coming. However I have a different kind of cramping only at night when I'm laying down and also a ton of white creamy discharge. Like way more than normal (sorry tmi). Also cervix feels very high, hard on the inner circle, but soft and swollen on the outside. I can't tell if it's open or closed. Help! I've taken 3 tests so far, all negative, but I feel it's still too early. Does anyone else have these symptoms?? And got a positive?
