I have been making out , dry humping while both being nude... I never miss my periods its always on time. My last period was on 1-1-2016 now its 3-2-2016 I'm 3 days late and I get cravings more than I used to. But we never really had any sexual intercourse rather than what I described above. Please help asap. We r not ready for kids but still willing to know. Coz I had a miscarriage on last October I can't handle or take any risk. I want to take care if something really happens. Urgent help needed.
