Am I crazy?? Advice please!

My husband and I are trying to convince our first baby and I need to know if I'm crazy or not! I had my period for February but wasn't nearly as bad as it usually is..I'm currently ovulating but I feel different..nipples are very tender, light cramping, nauseous after eating, so tired I can hardly keep my eyes open. My question is could it be possible to be pregnant even if I had a period for February?? I should mention this is our second month TTC. Any advice would be grateful...I'm also about two weeks away from my next period.
