Scared to test 😞

My boyfriend and I have been trying for about 7 months now (since october). My boyfriend and I were talking one day and I suddenly realized I couldn't remember the date of my last period. Come May 1st AF still hasn't showed up. Lately I've been noticing a few things that I'm not sure I should count as early pregnancy symptoms or not. I'm scared it's all in my head! The other morning I was lightheaded and had no idea why, then the smell of sausage made me nauseous (and I love sausage), I've had some lower back pain, headache, fatigue, moody, shortness of breath.. My boyfriend and I BD last night, when we finished and I went to use the restroom I noticed what I thought was the start of AF. But i quit bleeding within an hour or so and haven't bled since... I'm not sure what to think. I don't want to get my hopes up, I'm afraid of seeing snother negative. Opinions please?? 😕
