My husband and I are in the Marine Corps. 7 weeks ago he left for california and that was the last time we had sex. Obviously. Anyway, recently i've been experiancing symptoms like nausea, extreme hunger, can't satisfy my stomach, have had a period right after he left but havn't had one since...My back hurts, extreme mood swings, bleeding gums, headaches, chills, constipation, frequent urination, tender breasts, sore nipples, I "think" their getting bigger...Not sure what's going on. We don't use protection when we have sex so it's possible...But i've had a period... Could I be pregnant?
