We had unprotected sex last Jan 2nd, I took Nordette as ecp 5 days after the deed. I tested after a week and resulted to negative. I got my period on Jan 16th.
Then on Feb 20th, we did some sexual acts, no penetration happened but I am not sure if some semen came in contact with my private part. I tested on 2nd week of March, it came negative. I had bleeding for two days, on March 22nd and 23rd, I am afraid that it is implantation bleeding, so I took a test again after a week and resulted to negative.
