Feeling different.

So my period isn't due till Saturday, but after downloading this app back in February i was able to work out when I was ovulating and we did the deed on the right dates, I've been on weightwatchers and resting ALOT better than ever before, and I genuinely feel better (first week I lost 2.5lb!) but anywayyy, I don't wanna get my hopes up but I feel pregnant, I'm peeing a lot, feeling nauseous most of the day (exactly like my 1sr pregnancy), my nipples are sooo sore, I keep getting heart burn and I'm always so tired! I dunno how to explain it but I feel - different - does anyone know what I mean? Lol. I cant wait till Saturday to wait for AF but I'm going to and hope she doesn't show up! 🙊
