I'm trying to conceive fro 4 months , my cycle varies from 28 to 34 days , I have used ovulation kits and predicted my fertile period, got a positive result and went on to get a period , that was 2 months ago. Im really stressed about it and have been having sex at what I believe is the righ times.. please advise

Only 4 months? That's not really long enough to be getting worried. Most doctors say that if you haven't conceived in a year to start worrying. Pregnancy doesn't always happen so easily. Keep trying, don't stress. Enjoy the process.

It can often take a year to a year and half, and getting stressed does not good.

You're doing the right things. The only thing left is to be patient - the first skill to master before becoming a parent. ;)

Take my word for it - we tried for 18 months and lost 3 before having a successful pregnancy. Just enjoy the process and you'll look back on fond memories rather than stress.
