It feels like

It really feels like I'm pregnant the last time I had sex expect from last night was on the 15th. & now and some days ago I feel like I'm getting bigger and my stomach hurts more and more each day . & always feels like I gotta throw up and also now when I have sex I be all lazy. But idk if it's because I'm taking antibiotics btw today was my last day taking em. I just hope I feel better and I'm not pregnant
