Birth control, pregnancy, diarrhea, cramping, nausea

I've been taking birth control (reclipsen) for about six months now. I did have my period at the end of my last cycle, it only lasted for two days. It's been two weeks since then and I haven't started a new pack because I can't afford to buy the bc anymore. During the past two weeks, and before then, I have been sexually active. Ever since my last period ended much shorted than usual I've had diarrhea, cramps, gass, and nausea. Could this be a pregnancy symptom or just have something to do with not taking the birth control anymore?

I doubt it's pregnancy related but the symptoms are pretty harsh and have been consistent and progressive since the last day of my period. Not to mention my period was heavy for two days then stopped alltogether. I did skip a pill in my third week of pills before my period, and hadn't taken them since then, which is why I'm concerned it could have something to do with these symptoms.

I'd go to a doctor.. but I don't have health insurance anymore so I'm trying to find out all I can and see if anything helps it before even thinking about making an appointment.
