I found out at 3.5 weeks pregnant, hungover from a wedding. (Had no idea I was pregnant).
Up until that point I just had af symptoms, sore boobs and crampy. The only difference I found, was rather than my breasts getting sorer each day, the discomfort would come and go. And my CM wasnt doing its usual (which went- watery, EWCM, creamy, nothing, af) it just stayed somewhere between watery and creamy (I think people consider it 'lotion like') and is still like that.
I found out in the morning and by lunch time I felt nausea and sickness the following day the same but not so bad and now (at 4 weeks 2 days) all I have is slight sicky feeling in the morning when I wake. Sore breasts and lotion like CM.
Ive been getting headaches the last few days as well, and hungry- STARVING hungry since 7dpo.
