Hey ladies just looking for some advice on what you may think is going on.. 
Me an my partner done the dead last month when I was ovulating an I was die for my period on the 31st Dec, it didn't come until the 3rd of Jan, was very light and pink in colour it only lasted until the 6th of Jan.. I had a few spots on my panty liner a few days before.. On the last day of my "period" it was a light brown in colour.. Since then I have been feeling sick an tired all the time an my boobs are kinda tingerly. I've taken 2 pregnancy tests just after the bleeding stopped but both negative .. 
Anyone got advice or had anything similar happen to them?
