Well, if u had unprotected sex during fertile window, chances are pretty high, so get ready for sleepless nights, haha! Just wait for period date and take a test.
Medically speaking, there's only about a 25% chance of conceiving in each cycle even with perfect timing. Track your ovulation and if period is delayed, take a urine test.
I used to calculate percentages and panic after every cycle, but honestly, pregnancy only happens during ovulation window. If u timed it right, the chances are about 20-30% each month, so just stay calm.
It really depends on cycle and when u had intercourse. If it was around ovulation days, chances are quite good, so keep positive mind and wait for missed period.
I know the waiting game can make u feel so anxious and stressed out, and that's completely normal. Try to distract yourself, and if period is late, a simple home test will give u clear answer.
