hi.. i am 27 years old and i am trying to conceive from last 22 months. i went to doctor and i got checked where i appeared to have no fertility issues besides pcos and hypothyroidism which is usually in control after taking medicines and my husband has a really high count.i tried clomiphene for 6 months and one iui but no luck! Then my doctor suggested me IVF which also went unsuccessful (1 fresh and 1 frozen). Then we took a break of 6 months and tried naturally and went to Kuwait for work . Here we met other doctors who suggested fertiboost and metformin and cabergoline (while proclactin was 25).we tried for 6 months but again no luck! then next month our doctor prescribed us letrozole with trigger shots along with progesterone . AGAIN WE FAILED. This month our doctor prescribed us some fsh shots which are probably used in ivf with duphaston . I started taking duphaston from 14th day (15 july) but i started spotting from 21 july till date (26 july) . Today we did BHCG which was negative . my question is can possible while still start my periods while on duphaston?is there any thing to worry about? for sure i am not pregnant this month olso... Also i would like to add that meanwhile i also did hsg test two months back which was quite ok . my tubes are open and everything seems ok. Also i did one hysteroscopy which was olso normal (while ivf) Now my doctors say that my lining is thin for implantation . what could i do for that ? i mean how could i improve ? what could be the possible reason for this ?
