Should i test????

Summer
OK ladies... my hubby and I have been ttc for a year now. It's been really frustrating but for some reason this month is different. My periods r regular all the time. Well maybe a couple days give or take. But I always have pms symptoms a week or 2 before af shows her ugly face. Sore boobs, cramping, mood swings. But for some strange reason I feel nothing... the only symptoms I feel r slight cramping, dizziness, really tired, really bad heartburn and indegestion. Like it wakes me up in the middle of the night. So I'm just wondering. Could I be prego?!?!? I took hpt about 5 days ago but bfn.. should I test again today???
