Please please help!

So I'm on the pill, and I take it at the same time every single day. My boyfriend and I usually use condoms along with the pill, but lately we have been using the pull out method and he came inside of me a week ago. Ever since then, I've been having pelvic pain and today I had brown discharge. I went to the doctors about the pelvic pain and they said there was nothing abnormal other than some fluid inside my pelvis. I'm really concerned I'm pregnant and I don't want to freak myself out to the point where I miss my period. I don't know what to do! I'm planning to take a pregnancy test 10 days after the day he came inside of me. Have any of you guys experienced this? I need your support! Thanks again ❤️
