It is a natural process where fertilisation happens during ovulation, but honestly, every body is different. If you have been trying for a while without success, talking to a good gynecologist is the best way forward. They can run simple tests to guide you properly.
Basically sperm needs to meet the egg during your fertile window, which is usually mid-cycle. My husband always says to track the LMP and count 10 to 16 days after that. Keep track of your cycle, it's just biology working its magic.
Actually it's all about perfect timing and tracking ovulation, which used to make me so anxious every single month! Just try to stay calm and track your cycle properly, stressing about it only delays things. You will get your good news soon, keep trying but don't overthink like I did.
Mummy used to say that when the time is right, bhagwan sab perfect kar dete hain. Just make sure you are eating healthy and keeping your mind happy with family around. Nature does its work beautifully when you are relaxed.
Honestly I was so confused about tracking ovulation days and felt so much pressure, did anyone else feel like this? Now that I am in my second trimester, I realize we stress way too much. Just have regular contact during your fertile days and it will happen.
It happens when the egg and sperm unite, but honestly, sometimes the journey takes a bit longer for some of us and that is completely okay. Please be gentle with yourself. Your miracle will find its way to you in its own beautiful time.
