Missed period!

Hi all. My SO and I have been Ttc for about a year now. My period was all jacked up between March 2014 and January this year. Since January ive had a regular period once a month and I've done nothing different but oh well right our bodies work in weird ways. Well in May I had some tests ran showing infertility. My SO and I have decided to wait it out but now my period was supposed to come today and it's not normal for it to be messed up when it's been on a normal cycle for about 8 months now... So need some input I guess.. I've got sore boobs, not too bad though, backache horribly, bloating way more than ever, nothing sounds good to eat but I'm always hungry, I pee at least 3-4 times an hour, and I'm having major constipation for the past week. I don't know whether to think it may be pregnancy symptoms or just AF symptoms. I feel like they're a little more severe than usual. Input/ advice/ opinion please :)
