Hi, I m 39 yrs old, have been off iud for 1 yr and 1 month, my period was due June 22, it s now June 30. I ve had bad heartburn on and off, mild lower cramping, lower back pains, side boobs are sore and 3 days ago I had pink discharge only when I wiped. I took hpt 3 days ago, before pink discharge and BFN. Please give me your thoughts on this. Thanks.
