could I be pregnant?

So me and my boyfriend have been having sex every day sometimes twice, or on day we both have off work like a Sunday likes so then like 4-5 times, I had my last period on 16th of June, and my next period is due today I’m praying i am pregnant, itsonly the second month trying though, and I’ve felt different then any other time before my period, everyday this week I’ve felt so nauseous, lower back pain, breasts hurting etc but then I feel like this is all period symptoms too however the day before my period I usually always get really bad cramps and headaches but I haven’t yet? I’ve also put on so much more weight even my mum has noticed I used to be 8 stone and I’ve gone up to 9 and I have a fast metabolism and can’t put on weight so I’m so confused. All I hope is that I’m pregnant but I don’t want to do a pregnancy test and be let down I’d rather my period come and find out but I don’t know what to do help!!
