MY HSBAND AN I HAVE BEEN THINKING ABOUT HAVING A CHILD LATEL, SO WE DECIDED TO MAYBE START TRYING. I AM UNDER THE UNDERSTANDING THAT OVULATION STARTS 12-16 DAYS AFTER THE FIRST DAY OF YOUR PERIOD (MINE WAS FEB. 20TH), DEPENDING ON THE LENGTH OF YOUR CYCLE.....SO MY OVULATION TIME WOULD BE AROUND THE 4TH-7TH OF MARCH. SO WE DECIDED TO TRY TO GET PREGNANT DURING THOSE DAYS. WELL, MY PERIOD WAS SUPPOSED TO COME ON THE 20TH OF MARCH, BUT IT IS NOW 6 DAYS LATER AND NO PERIOD. iVE BEEN HAVING CRAMPS FOR ABOUT A WEEK AND 1/2 (FEW DAYS BEFORE EXPECTED PERIOD ON 20TH, AND 6 DAYS AFTER MISSED PERIOD SCHEDULED FOR THE 20TH. IVE BEEN READING ABOUT THESES "IMPLANTATION CRAMPS AND WAS WONDERING IF I COULD BE EXPERIENCING THAT. I HAVE ALSO BEEN EXPERIENCED LOWER BACK PAIN HEAD ACHES AT LEAST TWICE A DAY, SOME NAUSEA, BUT NOT TOO MUCH AND LOTS OF A CLEAR DICHARGE LATELY. GOING TO THE BATHROOM 3-4 TIME DURING THE MIDDLE OF THE NIGHT ALSO. COULD I BE EXPERIENCES THESE IMPLANTATION CRAMPS OR ARE THESE JUST PMS SYMPOMS THAT ARE GONNA SOON LEAD TO AN EXTREMELY LATE PERIOD? BECAUSE THEY FEEL JUST LIKE PMS SYMPTOMS.....BUT IVE NEVER BEEN THIS LATE.
