My youngest son is now 15months. I stopped breastfeeding him 4months ago and have still not had my period. My husband & I were using contraception until recently when we decided to let nature take its coarse. We dtd on Dec 7th then he went away for work. On the 8th & 9th dec I kept feeling like a bug was in my bra as my nipple fluttered! I didnt think about any possibilities again until I got thrush at the end of dec then nausea & cramps every day from 4th jan till today with diarrhea & bad cramps yesterday that have eased today but still nausea, crampy, yuck taste in mouth, itchy roof of mouth, excess saliva & gurgling abdomen. No period yet & Pregnancy test was negative 2 days ago. Any ideas on what the hecks going on?
