Hello doctor,I had unprotected intercourse two days after my period. The first time we used the condom, the second time without and did the withdrawal method. I took the action about one and a half an hour later. I do not know when I was ovulating and did not think it could be my fertile week. I started bleeding five days later and it was light and pink then has gotten heavier and turned red and moderate enough to soak a panty liner. I have taken HPT twice and both showed negative. Is this implantation bleeding or withdrawal bleeding?
Hello. If it was your second day of your period and you take an emergency pill after intercourse that it is with ChatDoctor.  Your period can be irregular this time and may take two to three cycles to get regularize and maybe the next cycle will be normal depends on your body\s own hormonal cycle. If HPT (home pregnancy test) is negative then no need to worry, you are not pregnant and the second day of menses is counted as safe days of any cycle. So you cannot be pregnant during that period because of no ovulation during menses.
