Help I Just Need To Know This?!

Updated

On April 6th I had unprotected sex and my partner did NOT climax inside me. And I was stupid enough to have unprotected sex the very next day and I realized how terrible of an idea it was so I took plan b. On the 16th I got a heavy flow and I broke out with pimples so I'm hoping it was my period? I was having panic attacks and anxiety so I bought another plan b and now I feel like I am gonna start my period (my normal cycle starts on the 1st of the month) and 2 days ago I took 2 pregnancy tests and both were negative. This morning I had another anxiety attack so I took 2 more pregnancy tests and they came out negative. Am I just freaking myself out? Im never having sex again :(
