This is my first time ttc and I feel a little bit crazy...at what point when you’re late and still getting negatives do you call the doctor and ask for a blood test? I have very regular cycles but I do take Zoloft for the 10 days before my period starts to help my pmdd, stopping the day my period starts, and I haven’t been taking it since the day it was supposed to start. I’ve also stopped taking other meds just in case. I tried two different types of tests just in case and all negative.
