Period pain and PMS but then no period! Total head fuck as we were TTC and then I had awful PMS and period pain. Thought "ah not this month". Then no period. Did a test (negative), so thought I was anemic as hadn't been eating meat. DH came home to find me cooking beef and was all
. A few days later I did another test and got my BFP. She's nearly seven now 
Next time, I don't think I had any symptoms. It was a surprise pregnancy and I didn't know a thing about it till I missed my period. Did a test and got a faint positive, but just knew it was positive. Told DH who didn't believe me as it was so faint. That baby is now nearly four! Take THAT doubting DH
