I had a medical abortion on Dec. 18th and i had my follow up on Jan. 5th and the clinic said i was no longer pregnanate and everything was fine. I had sex and the condom broke on Jan. 11th and i took Plan B about a day later. Now it is Jan. 21st and i have had very light brownish red spot bleeding. I do not know if this is implantation bleeding or my cycles are just out of whack due to the abortion and Plan B. Could i be pregnante ?? I took a urine test today and it came out negative, is it to early to tell, when can/should i test? PLEASE HELP.
