Seeking info on Ovulation and Proper use of OPK

Monika

Hi

Sorry for the long post. But i am so distressed and want to explain properly to get good suggestions.

I am 31 year old and i am trying to conceive from last 2 Months. I have been using OPK kit to find out most fertile days and making relation on the days shown as High LH surge days on OPK. But both time no positive result. So, now i am confused whether i am calculating my Ovulation day rightly or not?

My question is: Do we ovulate on High LH surge day shown on OPK or 24 to 48 hour after the LH surge? Can Anyone guide me of proper approach towards conceiving on the basis of info provided below?

My periods are regular with 4-5 day length. I keep my record of period cycle in <a href="https://play.google.com/store/apps/details?id=com.glow.android">Glow app</a>. Based on that i always get high LH surge on OPK only for around 30-36 hour, just 2 day prior to predicted ovulation day. So, can someone suggest me what would be best days to try. In last cycle we tried 3-4 times within first 24 hours of High LH surge day1. Second day LH surge was high only for few hours making it in total 30-36 hours of total LH surge. So we tried 1 more time next day while OpK was showing positive. The same 2nd day we tried 2 more times in afternoon and evening when OPK was showing no LH surge.

Then we tried 3rd day as well in the morning only which was the ovulation day as per <a href="https://play.google.com/store/apps/details?id=com.glow.android">glow app</a> data analysis.

We also had intercourse two days prior the day when LH Surge came as positive.

Note: I have been married since 2014. I accidentally conceived same year just 2 month after my wedding and went ahead with taking medicine for aborting pregnancy just after 10-15 days of first missed period.

After that i have never taken any medicine as birth control and never used Condom. We just using withdrawal method. Even in between we never planned pregnancy. And now, as i am trying to conceive from last two month, it’s not working out.

Please give your valuable suggestions.

For the next cycle, as per App analysis, my ovulation day is predicted on 1st August.

Thanks
