I had sex 4 times last month. Feb 11 & 18 (unprotected and had ipill both times) 26 & march 9 (protected) I had my periods on 12th feb and on 28th Feb I had period like bleeding (comparatively low flow) I had pregnancy urine test on 4 march and 18 march and 30 march, all negative. On 13th march I had brown spotting for 2 days and on brown discharge after that. Now the discharge is clear white. I'm feeling bloated, nausea and vomiting like feeling, lost appetite and stressed because of late periods. I just want to know that the urine test I did, should I rely upon them? And what's now my actual period date is? 13th or 28th? Could I be pregnant? Should I be worried or its just double dose of ipill messing the things?
