Maybe pregnant!!!

Me and my boyfriend have been sleeping together for two months now and I am on the pill but not perfect so I have missed a couple of day’s here and there. I have been lower stomach cramps but I don’t start my period for a couple more weeks and I have had blood spotting. Me and him will be so involved in the feeling that his pull out game sometimes doesn’t go as planned. We got the plan B pill but when I got it I got it two days later and then we ended up getting distracted and took it a day later which was 4 days after sex and I haven’t felt right since. Another week or so and I’ll take a pregnancy test but (been 6 days already) wish me luck! He already has a two month old daughter. We don’t need a child right now!
