Trying to get pregnant


Could I be pregnant? This is last months and this months I had sex last month four days around my ovulation. This month nearly everyday. I start my period in five days. I’ve recently had sore breast but I also did last month and I ended up not pregnant. I’ve also noticed I’m starving like crazy which is weird for me. I’ve been feeling sick and running to the bathroom like I’m about to throw up but nothing happens. I just threw up my food like 15 minutes ago but I’m still not sure. I didn’t get pregnant last month so I’m wondering if there’s something wrong I had sex I’ve had sex every day nearly this month I don’t see how I wouldn’t be pregnant but I’m thinking I’m going to start I’ve had slight cramps last month they were really bad.

Can someone please give me advice tips info anything??
