I got my last periods on Aug 9th to 12th after which on the 14th my boyfriend touched my vulva by that time he had some pre-cm on his hand so therefore just to be sure I took plan B on 16th Aug. On 23rd I got a very light bleeding that was almost like a clot which was dark brown in color, this continued for 4 days, after which I had heavy bleeding (26th to 30th) like my usual periods with lots and lots of blood clots. Can I still get pregnant after this? also when should I be expecting my next periods? (I am 21 years old and over weight - 170 pounds)
