7dpo extreme bloating and fatigue

I haven't been charting as religiously as I should have been these past 2 months, but according to glow I am 7dpo... Though I think it may be more like 9dpo.  Either way I get my period in a week, and I am having severe bloating.  I am a small girl and I've never weighed over 130... Well I got weighed at the doctor this morning and I weigh 134 lbs (up 6lbs in a month).  I haven't changed my eating habits etc. so I have no idea why I would have gained weight.  I feel almost like a cold is coming on, extra anxious, low dull cramping on right side, shortness of breath, EXTREMELY tired. My boyfriend and I are not TTC but we use the pull out method which isn't the best way... Could I be pregnant? And yes we did have sex a few times around ovulation.
