I found out at 4 weeks but through the whole first trimester I was either crazy sick or had absolutely no symptoms. I had a friend who tested negative on every test until she was a few months along.
Oh wow cause I'm 71 days late and I spotted pink a couple times not in a row like 2 weeks apart and I took test all negative and I been cramping here and again the whole 71 days late there will be days I feel nothing
With my first, I didn't have any symptoms until morning sickness hit so I took a test and it was positive at 10 weeks. I hadn't even missed my period yet. This time, I didn't have any symptoms but I tested for fun a week before my period was due and I ended up with a positive. I didn't get any symptoms other than a missed period for another couple of weeks.
