Mom thinks I'm pregnant

I'm 14 and my mom thinks I might be pregnant. Here's the story and sorry if its long. Me and my mom have a very open and easy relationship because its mostly me and her against the world right now. Anyway she just asked me out of nowhere the other day how I was feeling and I admitted I had definitely felt better because I had been such for a couple days which is unusual for me anyway she said she had noticed because I'd had a stuffy nose and had been throwing up or nauseous or light headed at random throughout the last few days and my moods were definitely off. She also asked if I had had any cramping and asked about the little bit of spotting I'd had a couple weeks prior and I answered honestly that I'd had a little pressure and cramping in my lower abdomen area she said she though I might be pregnant and asked about my breasts and mentioned they didn't look like they fit in my shirts the same way as usual (she checks my outfits in the mornings before school to make sure there appropriate) and asked if they had been sore or if I'd noticed anything different and I answered yes to both then she asked about my bathroom frequency and asked if I had also noticed my increase in trips at home. She says she'll buy a test in a few days just to be safe because conception would have been early October when me and my boyfriend had unprotected sex the first time id ever had sex and only time we've not used a condom I've also had a difference in discharge amount color and texture but idk if that tells much my school doesn't do sex education other than tell you not to do it but we also have an in school daycare due to the amount of teen pregnancy in our county. I was just wondering what all you fellow glow users think about my condition and I also don't want to be lectured on me being "too young" it was my personal choice and I have no regrets and will not be having sex again for awhile because its just not really for me right now. I'm asking for help not a critique.
