My last period is started on oct 7, 2016, and we had intercourse on oct 24 but we did a pull out method, had a bleeding on nov 4, for 2 days. I dint know if it is implamantation or what then. Got a bleeding this december 11-12 yes two days only.. I have symptoms like bloating, back pain, head ache, fatigue and short of breath other than that, i dont have any symptoms.. Am.i pregnant? I read that some still bleed for a short oeriod in their first trimester?
