I didn't know I pregnant too. Cause my menses always irregular. Then happen that's two days I keep having diarrhea and vomiting till super bad. So I went to clinic to see a doc, the doc say want check for pregnancy so I said ok, then it shows positive, I was so shocked and I tell doc not mine, so she do one more time for me and it shows positive again. At first I was so happy and wanted to tell me bf and though he will be happy like me but end up sigh, things just go differently till....I will tell myself to be strong mummy! How about you? How you found out ?
