Could i be pregnant?

OK so first my husband and I decided a few months ago (over 8 months ago) to start trying because we weren't using protection or being cautious about getting pregnant. Almost immediately I was late for my normal cycle ( about 35 days give or take a few days) so we took the test and we had 2 lines and so I was beginning to cramp the next day and so I took another test and the 2nd line was faint but still there and then I began to bleed. We went to the hospital only to find out they were false positives and my hgc levels were 0.00% and I was never pregnant. We were crushed. Fast forward to this cycle. I'm a week or so away from being a month late. I'm wanting to stuff my face but I feel full all the time. I'm bloating but not as much as I do for my period. My nips are darker and sensitive but not veiny. I get this weird stomach ache that feels like I've eaten too much but also like I haven't eaten in years and I'm emotional and moody but not as much as with my period and for my PMS my cramps are bad like fetal position in the tub crying and gagging bad but I haven't had any cramps at all. I've take 3 of the first response tests and all were negative yet still no period. Could I be pregnant? My husband and I are trying hard not to get our hopes up for fear of another false positive. And also right now I have no insurance because I was on my dad's plan and he's not working anymore so I was taken off and my husband can't put me on until open enrollment.
