Hlo sir agar period irregular ho toh ovulation time kaise pata kare meri pechli lmp 24 dec us se pechli 18 ya 19 november us se pichli 21 october ko thi. Maine 10 th jan ko protected intercourse kiya tha 30 jan tk period nhi aya toh beta hcg test kiya woh negative tha uske bad maine crina ncr ka 5 day dose at night 30 jan se 3 feb tk complete kiya. Kya sir pregnancy ki koi chance hai sir kyun ki meri period is ee pehle miss nhi hue kabhi kya maine beta hcg test sahi time pe karaya urine test bhi 3-4 jan ka morning sample negative hai. Beta hcg test se kab pata chalta hai or meri ovulation kab hui hogi.
