Q1:
B. ectopic pregnancy

Yes. Although her period may be slightly delayed due to her illness, the history of previous PID puts her at risk for an ectopic pregnancy. If her last menses was a normal period, the presentation would be too early for an ectopic pregnancy. However, she had scanty bleeding 5 weeks ago, which may have been due to early gestational bleeding. If the diagnosis of ectopic pregnancy cannot be ruled out by pelvic examination, a pregnancy test should be performed. There are also other correct options. Have you found them?
