Letrozole month 5!

Hiya guys

Just want some advice and help -

TTC for 2 years - 5 months ago got referred to fertility clinic and started letrozole.

First month was 2.5mg twice a day and they couldn't see any follicles ready so was out that month. Same again next month.

Month 3 they told me to take 3 2.5mg a day and then I produced 3 follicles which were too mature so was told again don't BD.

Got told to alternative it so 2 3 2 3 2 - but was away so I couldn't check that month so don't the same the next month.

I went to my scan on the Wednesday when the nurse again said 3 follicles 1 was 22 1 was 20 and the other was 19 in size.

Got told again that I can't do anything as I could end up with none, 1, 2 or 3 pregnancies. Having not known this me and my partner DTD on Monday and again on the Thursday as we've had no luck and I'm soon to finish. I also felt the ovulation on the Friday.

I'm not 8DPO and feeling no symptoms. Has anyone experienced this and got a positive? What are your thoughts??

Thank you so much for reading!
