<s>[INST] Hello, I was on the Microgynon 30 for the last 4 years. My last date that i was on my period was 07/10/2010. As soon as i finished i was due to start my pill again on the 08/10, however i did not take it again untill the 14 + 15/10/2010 just for two days.. I was intermite on the 15th & 17 + 18th October without taking the pill. I was due on my period on the 31/10/2010. On the monday 18th I felt symptons of Back Ache, feeling sick and little cramps. On the 25th October i got a little bit of spotting which was red. Then it stopped overnight and came again for a couple of hours in the morning. I then had like a period but was very brown and only lasted 3 days... I have been feeling very tired and dont know if it is just me thinking im pregnant.. I have tried 4 prg tests before the so called period and all neg... Dont know weather to try again... Please help. [/INST] Hi, I have gone through your question, and I think I have understood your concern. I will suggest you the best possible treatment options. 1) As you had unprotected sex in this period, there is risk of being pregnant.  But I will suggest that you get the urine pregnancy test done Only after your expected date of the cycle.  2) doing the tests before the expected date will not give proper results. I will suggest you to get urine test done 15 days after the last sex act which was on 18th. I hope this answer helps you. Thanks Chat Doctor.  </s>
