i Would have to agree i found out i was pregnant when i was 4 & 1/2 weeks and i was feeling symptoms and some cramping in my side thought it was gonna turn out to be my period but i was feeling the begininng of pregnancy! GoodLuck : )
Some people will tell you pregnancy symptoms don't start until you're 5-6 weeks pregnant. I personally don't believe it. I've felt them earlier, so I guess it really depends on you if you think you can feel them sooner. The best thing for you to do is wait until your period is due and take a test. Good luck to you!!!
It could be implantation cramps but sometimes we have cramps after ovulation for no reason. I think that you will have to wait until your period is regularly due and then take a test... It is possible that it is implantation! Pregnancy symptoms don't usually start until anywhere from 5-8 weeks but sensitive women (I felt mine right after implantation believe it or not!) can feel it at 4 weeks or so =) I have my fingers crossed for you!
