Definitely cd 13 in my opinion. Depending on your age id say you ovulated anywhere between cd14-17. Just realised how long ago this was but hopefully you got it xx
No I'd say that's perfectly normal to worry until af due date passes. Easy to think that you'll just get your period anyway despite the test. All 7 tests are definitely right haha
And then the worrying until every other milestone passes. I was like that with dd and this baby too lol. Just try to relax and enjoy it all. Fx for a healthy 9 months.xx
