I recently took a pregnancy test for the first time. I'm now 15 days late for my period. However, the test showed negative. Honestly, I was kind of disappointed. My long time boyfriend and I had sex 3 times last night. Usually, we use the pull out method but twice last night we decided to really just go all the way and he didn't pull out the last two times. This is a first for me and I really felt connected to him. I'm still wondering why I didn't get my period? I have had no pregnancy symptoms but thinking after last night I could start to develop them? I have one pregnancy test left, when should I take it? I could really use all the advice I can get.
