TTC can be a fun but stressful journey! Mine lasted almost 4 years! I never found discharge to be a great way to judge. One thing I did that really helped was take my temperature. That is a pretty reliable way to know if you have conceived or not. Your temp goes up around ovulation and will stay up until you are getting your period . . . unless you are pregnant. And then it stays up. Mine has stayed up twice in my life. The two times I was pregnant! You take it first thing in the morning. track it. You are probably at the point in which your period is due, so can test. Let me know, Okay?
If ovulation occurred on 6/22- you are pretty close to when you would be able to take a test and get a positive. It's possible you might get one now, but be prepared for a negative- just in case. I'd try to wait a few days and take a test, follow up with another test a few days after that. Best of luck to you!
