I think that it is too early to go with the assumption that you are pregnant. I think because you are worried about it and thinking about it, that you are noticing every little thing and assuming that you are pregnant. If your period is scheduled to come next week and you are cramping, it may be your body telling you that your period is coming. Cramping in pregnancy doesn’t come that soon. And FYI….just so you know, it isn’t the actual semen that is needed to get pregnant, you can get pregnant by the clear stuff that comes out during sex, before ejaculation. I don’t know what it is that you want, if you want to be pregnant or not, but either way, Good Luck and I Love You.
