Am I okay.

So currently I am crying my eyes out. I am so stressed. I haven’t had a period since May 25th. I had unprotected sex on June 19 (but he pulled out and did not finish inside of me) and I have been worrying about being pregnant literally since that day. I have taken 4 pregnancy tests, and they have all been negative. I have had watery discharge, and today my boobs have been kind of sore. So I am really really worried. I have a appointment with the gyno August 8th to see about getting on birth control, but do you guys think that I am okay? Should I take another test? I’m so so very stressed that it’s making me lose my mind. I think about this 24/7. Please give feedback.
