TTC for 4.5years...

Ive been TTC for 4.5yrs now... (im 26 and have 1 wee boy at almost 7yrs old) weve suffered 2 miscarriages aswell... i dont even know differences in my symptoms now cause its been soo long. Ive been diagnosed with PCOS recently so currently on my second round of clomid. Took clomid few years ago and fell pregnant tht ended in miscarriage so im hoping its same this time round (minus the miscarriage of course)

Anyone got any (even weird) tips that may help??

I am currently due on my period today but last night was a BFN
