This time around, so weird...suggestions??

So last month I posted about possibly being preggers but ended up just getting af a week late from getting my brain all tricked into thinking I was (at least I assume this cus I'm usually very norm, 28 day cycles). Anyhow my bf nd I weren't kinda disappointed so we weren't trying but we weren't preventing whereas last month we wore condoms. So after the chaos I totally just forgot about obsessing and just went with the flow seeing we had a lot going on anyhow, it was perfect! Well now AF is supposed to be here on the 31st it says on this app and the 1st on another but I'm having some legit symptoms..breasts almost feel lumpy but long smooth lumps, itchy nipples, sneezing soooo much and eating everything in sight! Also have the cramps nd stuff but that could be anything really...what are your thoughts??experience??
