Am I positive?!

Sarah • Been with hubby 7 years & married 3. Luna Violet 💗 horn Oct 2015 (conceived with glow help!) & River Elijah 💙 born Aug 19 2017! Both natural !! 🎉
So I just took a test because I've been having cramps but it's before my period is supposed to start which is strange. But we've only been TTC for a month, and I'm only 9 DPO cycle. (This may be TMI but I took the test about an hour after we had sex, could that make a false positive?!) I'm so nervous I almost can't believe this is happening. What do y'all think?!!
