So I've not seen my period since 16th of december which makes me 10 days late according to the app. I bought a test four days ago and have been itching to test, my plan was to test Monday morning, but I caved this morning, took the test and got a BFP, it was weird because as soon as I dipped the stick in my pee the lines just went crazy and b4 30 seconds were up I had two pink bold lines. I'm excited but nervous at the same time, I have type 2 diabetes and fear I'll mc again.
