I was so sure?!

Been TTC #2 for 6 months, was so sure it was going to be a positive this month; had cramps, had sex either every day or every other day during cycle, had a positive ovulation test and nipples been incredibly sensitive the past few days. I was so sure I took a test today even though AF not due until Monday and it was a BFN! So gutted! I hate it when u convince yourself it's going to be positive and it isn't! 😩😭
