Pregnant or PMS??

So I stopped taking my BC 2 months ago after only being on it for 3 months because it made me feel awful. Since then we've been actively trying to conceive. Last week I had dull cramping on one side and my chest felt heavy and since Saturday my face has been breaking out like crazy and I've been a bit more sleepy. Before BC I hardly had PMS symptoms so could this be effect of coming off of it or pregnancy symptoms? I'm going to test next week but for now just curious.
