Could i be pregnant? having tender cervix, preg symptoms, late period last month lasting 2 days then this month spotting that was brown lasting a day

When in doubt: just check pregnancy test. And if you are still not bleeding normally and first pregnancy test was negative, check it again in 1 week. If both negative and your symptoms persist, get to a GYN so they can help you determine what the next step is to regulate your period and minimize the adverse symptoms that could be premenstrual dysmorphic disorder (PDD).
