If you feel ovulation (mild cramping on your left or right side) should you have had before or after this?

I never really took any notice of my monthly cycle, until I started ttc. I used to have an almighty pain once a month. I used to be in agony for a couple of hours, and would have to take strong painkillers, so soon as I started to chart my bbt, and take notice of when I was about to ovulate I realised that these pains every month where ovulation, I had my mirena coil taken out in December to start trying. Apart from one time a few years ago I have never seen any EWCM, and started to panic that I would not be able to conceive because of this so I decided to buy pre-seed. Yes the egg does live 12-24 hours so I would suggest to you that try and work out when you are about to ovulate and try an BD the day or so before ovulation on the day and the day after. To increase your maximum chance. I am now 6 weeks pregnant tomorrow I say that it was because of the pre-seed we only used it twice. Good luck hun relax and it will happen x
