Hello, I indulged in incomplete unprotected Penetration (1 inch) n he says there was no ejaculation (also I didn't feel any). Had ipill at 36 hours. Then I got my period heavy n dark bright red at 36 hours (little brown in beginning) after 15 days. One month post this period, I again got periods dark bright red but little lighter (2.5 days than usual 3 days). I m feeling v tired for the past 1.5 months n also gained weight.. My breast size has increased slightly. Can I b pregnant as urine tests were negative. Please help urgently.
