Help!!!!

Nitzaliz • Due Dec 1st💘
So hubby and I stared trying in December, my last period was nov 26 thru the 1st. For the whole month of December I didn't get a period. I also tested and got a bfn! Came January the 2nd and here comes AF the only difference this time is that the first 4 days was super light and after that it came medium/heavy! I got my period on the 2nd and today January the 11 AF is still here and heavy! So frustrating because hubby's birthday is on the 19th!
