Hi Phy,
I don't know your definition for awhile, but I tried for 1 year and nearly give up and wanted to schedule a appt with a gynae to check wat wrong. Bingo I was pregnant. Both my HB & I were 33+ when i am preggie with 1st child.
We had a theory on how i managed to get pregnant, but I don't know whether this works for others.
I used the below method for 3mths after reading others' experiences over the web and consolidated some advices from preggie mums:
1. monitor your ovulation week with the help of Ovulation Predictor Test Kit (OPK) for 3 mths to pin point your ovuln wk. I used Ovulation (LH) Predictor Test Strips which is cheaper than midstream type. Strips can be purchased over the internet at a cheaper rate. You got to test daily from the end of last menses to the start of a new menses. My Ovln day shifted mth to mth, but always within certain wk. You then plan your sex life around that week. Every 2-3days once.
My period days can be 30 to 35 days from mth to mth.
2. pre-empt your ovulation week with the help website that can provide u with a projection of your fertile week.

3. After your HB ejaculated, immediately rest your legs on your bed headboard, kept your hip tilted up with a small bolster. Try to do this exercise to faciliate the flow of semens into your cervic. I dunno how to describe it but it is like stopping your urine and then release and stop and release. The idea is to create a suction within u to suck the semen towards the cervic to increase chances of preggie.
4. Always change your intercouse position. For some missionary doesn't work well. My HB attributed his success to the doggie position, from the back. u know wat i mean, right?
I hope this would help. I started off quite ignorant of how we can get pregnant. I tot we just did it and we will get it. Somehow, after 1 year of trying I didn't. But after adopting the above routine, I finally preggie. I will be on my 18wks preg tomorrow.
Good luck!
