I had sex with my bf on February 8th. Within few hours I took an I pill. I started bleeding lightly the next day and bled heavily between 12 and 16th of the same month. I had sex with my boyfriend again, a day after the bleeding stopped. I did not take a pill this time. The bleeding occurred a week before my period. I haven't bled since then. My period is really late and I took a home pregnancy test which turned out to be negative. I took two quantitative bhcg tests. Both showed my bhcg levels under 1.5. I feel really bloated and I have been belching a lot. Is it possible that I might be pregnant? I took the last test on April 4.
