Verdict on pre seed!

In have been trying for about 8 months, I have had 3 previous miscarriages and all pregnancies I caught very quickly. This time round it's taking much longer and I'm beginning to think I have secondary infertility.. I have an appointment with the genetics doctor in a few weeks but thought to use the pre seed this time.

I used it last night and I done a cervix examination this morning and it's rather high up and very soft. To me it feel open as it had a Grove in the middle of it.

Just out of curiosity does anyone find that pre seed helped?

Thank you for your advice in advance
