Hi everyone, about one month ago I began taking prenatals in preparation to conceive. Although I've had some longer cycle lengths in the past for the last year everything has been regular to the day. This past month was our first month TTC, I had one FRER test with a faint line at 12 DPO every test then is negative. My period is the over week late and I'm obviously not pregnant. My question is, is this concerning? Could it be my pretnals affecting my cycle delaying my period? What are the odds my first month TTC, my period is late but not pregnant? I know it could just be late and be that simple but it's unusual since I have been having regular cycles for so long. Thoughts?
