Hi gals, I apologize to just jump in but I have been stalking and saw Ttc's pics....
Both those cycles (I honestly think) were chemical pregancies. A line is a line especially when you get clear negatives after AF, with the same brand tests!
The reproductive specialist I'm seeing now, put me on baby asprin (81mg) throughout the luteal phase because it kept happening to me too, 3 times (light lines but then AF arrives). He tested me for a bunch of blood clotting factors and one turned out to be positive which means that even though fertilisation might occur; as implantation starts happening, minutely small blood clots in the uterine lining stops the embie from getting enough blood supply to properly implant. This then results in a chemical pregancy.
Maybe you can try taking baby asprin in the luteal phase too and see if there is any change?
I asked him about any side effects of doing this and his reply:
*you might bruise slightly easier
* 81mg asprin will have no anti-inflammatory effects so will not stop pro-implantation prostaglandins from developing (good for implantation!)
* all it does is prevent slight blood clots which could cut off embie blood supply
* It will not cause or exacerbate stomach ulcers because of the low dose
* it can even be taken throughout the whole cycle
* ALL his IVF patients are on baby asprin regardless, it increases the odds of a sticky bean that much! But ONLY at that low dose, otherwise the mechanism of action changes.
(Just don't take it if you have a bleeding disorder like haemophilia).
I have been rooting for you all so much esp because I'm also ltttc and I know how hard it is. I have stage 3 endo & endometriomas so that has been my main problem.... I'm going to ttc again now as from April, after having just had surgery and I will be chugging my asprin!
Hope that this advice might benefit some ttc lady somehow. Fx for you ladies xx
