2nd miscarriage! Can anyone advise me on what could be the reason

Zee

Sorry for the depressing question but really need some advice! I am currently in process of my second miscarriage! I just wanted to ask if anyone has been through the same situation and what was the cause of it (medically) if found? My doctors said they don't investigate until you have 3 miscarriages!

Sorry for sounding negative as I know it's not what all the mums would like to read!
