It's possible. I'm not sure how long i was late the first time but i was about a week late the second time and i wasn't even late the 3rd time, i wasn't due for my period for another 3 days but got my BFP but lost the baby at 3 months. I didn't know i was pregnant the 4th time until i miscarried. I would just wait a few more days and test again. GL
Queentdi: bfn - Big Fat Negative and bfp - Big Fat Positive.
The first one, I didn't realize I was pregnant, and I hadn't had a period in years, so I honestly don't know... and I can't remember. :/
This second pregnancy, I hadn't had a period in about 11 months, but going by the period dates I had right after I had my son (I only had about 3 cycles) I was about...a week late.
