So we've been only ttc for 2 months now ,well I had 2 periods in one month in January than ran into the beginning of February. Both apps I use say I should have started by now. To this app I'm one day late to the other I'm 4 days late. I've never had an issue with my periods even after pregnancy with being late or never on the correct date. Every test that I have taken up until 3 days ago have been negative. I dont want to waste anymore money on expensive test with only getting my feelings crushed. Has this happened with anyone ?
