Irregular Periods After Unprotected Sex: Seeking Medical Advice

Question
17yrs old.0 children.12-1-05. I had unprotected sex 4 and 5 days after my period ended(12-5-05) with my boyfriend i had one day one day of bleeding that month(28th). I havent had my normal 5 day period since then which is why i need your help. I have had two days out of the month where i bleed since Jan.25th and 26th. they are shorter and lighter than my normal period. Now i have seen a GYN just yesterday and if it wasnt the most rudest and horrible doctors appt i have ever i dont know what it is after waiting for 2hrs just to give a urine/blood test and blood pressure taken and a pap done he didnt even let me explain whats been going on nevertheless tell me whats going on all he does is give me Birth control pills and says come back in 3mos. didnt explain how to take them or when. now i know id be to young to get pregnant but i know my body and something still isnt right after i got home from my appt i called another OBGYN clinic and they told me not to take the BCP till i get another opinion and more information on whats going on which works for me. My mom is looking for me another doctor because you should see my stomach i am huge! and this isnt bloating  i have it before and this isnt it i have also never been through this before till back in Dec is where it all started i weighed 99lbs back in dec. as of yesterday i weigh 126! which is a big shock for me and everyone in my family has noticed it so i know im not going crazy. If you could please me in this situation i would really apperciate it so much becuase i still feel im pregnant and still need a lot of answers. Also since he didnt tell me this either when should i recive and results back on blood work and pap smear? Is there a possibilty im pregnant even with this urine test showing neg? mom even suspects im pregnant i just want to get the care i need and if iam pregnant the care my baby should be getting. Please help

Answer
If y our last period started on December 1, by  now a urine pregnancy  test would be accurate. If it was negative, you are definitely not prregnant.Did the doctor do a blood test for pregnancy? If that was negative  you will know for sure. Birth control pills are safe even if you are pregnant until after 12 weeks pregnancy. If you were pregnant, you would not be 20 weeks pregnant and you would definitely see a five month pregnancy (at the level of your belly button). A sonogram would see a fetus and a fetal heartbeat in the uterus. If you are not happy with your gyn, see another one.
