I'm 33. The first day of my last period was May 22nd but hasn't been too regular in the past several months. I had intercourse June 8th without protection. It's now June 30th and I haven't started my period but this is the third day of moderate to severe cramping and very little spotting. I also feel low back pain once in a while. Yesterday I had one time of 'a lot more than spotting' when I went to the bathroom.
I took a pregnancy test the day I thought I was due for my period to start and again on the 26th, both negative.... should I make a Dr's appointment, could I be pregnant, a miscarriage, just late?
