Hello. Back in April I had Sex with a condom but I was afraid some had leaked out (I am quite paranoid). This resulted in me taking one levonelle pill, twelve hours after sex. A couple weeks later I had what was like my typical period, heavy bleeding and no cramps (my usual). Now, a few weeks, later I had a single spot, and some cramps. What is the likelihood ( I know not super accurate unless I take a test) that these are pregnancy symptoms.
