I had sex. So there are few uncerain things happened to me... I wann to know what is it?

1. I bleeded like red gooey chunk two times in two days ( very little).. on third day I bleeded heavily ( so much that I changed 2 pads in 2 hours ) so is it Implantation bleeding? Because I didn't bleed next day.
2. what if my periods come after Implantation bleeding? Will I still be pregnant??
3. can I be pregnant even if he used condom and did not ejaculate inside me? ( it was my 1st sex).

Please ans these questions.

1. This is not normal implantation bleeding but no two women are the same. Perhaps bleeding if this was the first time you had sex.

2.It is possible to have at least the first period after having sex and/or implantation bleeding. Not always as common but possible, esp a lighter period

3. very easy, condoms have s 2 to 18 percent failure rate ( right off planned parenthood web site) and pulling out only lowers sperm, since there are plenty of sperm in the early fluids.

You will just have to wait till time for your next period, if you miss it, you wait 2 weeks and do a pregnancy test, with first urine of the morning
