Anyone else experience this?

I stopped taking BC about a month and half ago. I stopped mid pack because I lost them and when I didn't have any severe side effects I decided to just stop taking them all together. Well, this month I have had on and off sensitive nipples, recent nausea thats not limited to mornings, cramps, and the smell of tuna has sent me running (although I was already nauseas at the time, but it made it so much worse). I took a first response test 4 days before my expected period and got a BFN. Also worth noting that partner said he had a low sperm count and trouble conceiving. So, my question is, has anyone experienced these side effects from simply stopping the pill?
