My husband and I have been TTC for 5 months now and I started using an ovulation kit which put my LH surge at February 8th. I had a positive test on Friday but I feel like it wasn't SUPER positive but I have also passed my expected period day. Since I'm too early for my first prenatal visit I'm trying to figure out my expected due date but when I put in the date of conception it says I am already over 4 weeks pregnant. How is that possible when I didn't even ovulate 4 weeks ago?!
