Hi, currently ttc. tracked my ovulation. my current symptoms: larger,tender breasts/slight nausea throughout the day & when i eat certain foods/headache/tired/much higer bbt (0.8 degrees higher, consistantly since symptoms arrived). could i be preg?

Hard to guess: A urine pregnancy test, done correctly, gives a reliable result 3 weeks after sex (3 weeks after when conception might have occurred), or 1 week after missing a period. If done sooner, a positive result is likely real, but a negative result may be due to testing too soon, and thus lead to a repeat test. If a woman gets her normal typical period, then she is not pregnant, and a test is not needed.
