My boyfriend and I had unprotected sex on the 28th and I took a pill on the 3rd day after. i should be getting mine on the 12th but I've had symptoms/ side effects that are shared with pregnancy and the side effects of the pill. I took a test but the manual thingy said the accuracy is like a 34% since I took the test 10 days before my period should get here. Any advice?
