Lol I know, you would think it was a simple matter of sex one evening and bam! If you were to believe anything school said, of course. And it can be like that for some, but mostly it isn't. I think it's far more usual for it to take time, and if you look at statistics they will tell you there's about a 37% chance of pregnancy on any given month where things have been optimum, I'm sure this is what I have read anyway. It's a minefield which is why it's such a miracle it happens! But, having said this, we are built for this to happen.
There are loads of different factors that play into conceiving successfully. Everything from nutrition and general health to stress to sleep to the timing of sex. It's difficult to avoid looking into things in more detail I think, especially when you want something so much. But this isn't a negative thing, as it can give you a lot of insight.
I didn't have a clue about temping and checking cervix position and am still relatively new to it but it isn't as difficult as you may think. I find cervix position more confusing as it can be difficult, unless it's blatantly obvious, whether it's soft of medium or firm. If you want to start then I think the best time would be when you get your period, simply because usually it's low and firm and is a good comparison to remember once you are hitting your fertile phase. I have noticed mine is very low and firm during af (which sounds gross but I also attempt to use a menstrual cup, so it's tough luck if I want to use one of those lol!) and the difference to when I'm about to ovulate is huge as then it will be much higher (I will have to push to feel it, as if trying to poo. Sorry, way too much information there!) and soft and will be open. It's the bit between ovulation and next period I get stuck with, because cervix position seems to vary for me.
Temping is quite simple to do. If you download Fertility Friend or a similar app which allows you to note your temperature on a chart, you will start to see a pattern forming. Your temperatures generally stay on the low side before ovulation, then after ovulation they should go up and stay up (or higher than before ovulation but they may generally be up and down, just won't be lower than before ov) because this is when progesterone takes over to keep your temps nice and high in order to prepare for and sustain a pregnancy, should it happen, until the placenta can take over (I *think* I have this right). If you don't conceive then your temperature will dip right before your period. This I think can vary slightly, but on the whole of you aren't pregnant your temps shouldn't stay elevated past when you get your period at least.
You should use a basal body thermometer for this as it has two decimal places which can gauge a more accurate reading than a regular thermometer. These are cheap on places like Amazon (I think I paid about £5 for mine). If you decide to give it a try, you should take your temperature at the same time (or as close to as possible) each AM, before you do anything else, to avoid raising you temperature since you want to gauge your temperature base. You also should have had at least three hours' uninterrupted sleep beforehand too. Best place to take temperature is under your tongue.
Also, beware of the cheap pregnancy tests you can buy online as these can be unreliable despite claiming to be the most sensitive tests. They are fine for some people, but for others they aren't. Many see a line on all of them anyway, some don't see a line even though they may have a positive test using a more expensive and less sensitive brand of test, and most batches come with knocks and dents on them which can make it difficult to see an early, faint positive result. Or, it can make it look as if you have a positive result (especially when you invert the photo) when you don't.
If you are a somewhat of an addict when it comes to testing then as long as you don't mind the possibility of some of them being faulty, they are good because they are so cheap, but if you are a little more sensitive and would find yourself feeling disheartened easily then it may be better to avoid them and stick to testing when you think you are due your period.
Once you can pinpoint ovulation it should be fairly easy to pinpoint when you will see your period, or at least a relatively narrow timeframe for it to happen.
Sorry, I have rambled on.
Sorry also, it's difficult to say on ov, as you may have simply missed the peak, but I would keep testing for it and keep BDing, as it may be yet to happen
