So this month my husband and I tried the pre-seed lube. We used it every other time we had sex, until my fertile window ended. On Wednesday I had slight cramping. Thursday nothing. Friday slight cramping. My AF was due yesterday. I have had no more cramps since Friday. No sign of AF. I have been nauseous the last week and very indigested. I'm so tired and crabby. I have taken 5 pregnancy tests since Wednesday and they were all negative. Ugh. I hope my mind is not just messing with me. I have hs a steady 26 day cycle for as long as I can remember and am NEVER late. If I'm not pregnant I wish my period would just arrive so this anxious wait could end!!!! I'm going crazy not knowing!
