HELP NEEDED PLEASE! 😭😭

so me and my boyfriend have been having sex for the past 3 weeks, using the pull out method ONLY. We start foreplay and once I feel the tip in, it's too good to stop and grab a condom so we just get ahead of ourselves 😭
 In the past week I've been crazy tired and kinda sick feeling. I'm due to go to the doctors on Monday morning to get the pill but I'm wondering should I wait and see that I'm definitely not pregnant (hopefully not) before I get the pill? 
Btw I'm due my period in 2days and I had a spot of baby pink pee when I wiped this evening..
Thanks in advance girls! x
