Am I pregnant or gassy

[First_timer_maybe]

A couple of weeks ago I noticed my weight had increased and none of my pants fit anymore. I was very sensitive to smell mainly perfume and I love perfume. Well now I can't be in the same car or room if a person wears it too strong it makes me sick. Also my nipples and breast were very sore. Now my nipples stopped hurting but my breast hurt and are a little swollen.its hard to chart my period because I got on depo around sept17 and I had irregular cycles even skipped one I think but the last one I had on the shot was light. Shot ran out dec17. I know because I got a letter saying so. I have always been small mo more than 100lbs maybe . Well the scale says I'm 114  now. 14lbs in 3months?!?! My stomach has gained weight but I thought it was just me eating more. My girlfriend said I was spreading and I look wider but I haven't told her I think I'm pregnant. Last night I felt something like bubbles popping in my stomach and my stomach moved it did this 3 different times. Now I keep feeling a flutter in my stomach. Weird. And I saw a post from someone saying that they wake up sometimes heart pounding and I have noticed that the past couple months and weird dreams about my boyfriend. Someone help am i over reacting? Am I pregnant? Also I have endometriosis and I took a dollar store preg test but it was neg. Feedback please

You certainly could be pregnant even though the dollar store test showed up negative.

If you have consistently weighed 100 pounds and then suddenly gained 14 in three months,  you really need to find out what's going on even if you're not pregnant.   That's a LOT of weight to gain in a short period of time if you're not eating much more than usual.
