Missed period but negative pregnancy test?

It is possible that you could still be pregnant, but probably not likely. What I have found while TTC is that if I am thinking about it all month long or stress myself out thinking I could be pregnant the previous cycle I end up ovulating later than expected and therefore start my period later which once again gets me stressed out wondering why I am a week late and still getting negative tests. My best advice is to RELAX! I know it's hard not to think about it once you decide to start trying but it's the best way to keep your cycles predictable and not get worked up over a late period. I usually have 32 day cycles but once we started TTC and I was worrying about it and looking into every symptom my cycles starting being 42, 45, and 39 days long. Last month I decided to just relax, not worry about, and realize that it will happen in time. My cycle was a normal 28 days long and even though I didn't get pregnant, I felt much better knowing that I ovulated on time and had a normal cycle and didn't have to spend an extra week wondering why my period was late but I was getting negative tests. When I got pregnant with my daughter we had been TTC for 6 months and the month that I actually got pregnant we were so busy I had no time to think about it. I was 8 days late when I finally took a test and to my suprise it was positive! I had no idea and was sure that my period was going to start any day and it was just late because I had been so busy the past month. Good luck and I wish you the best!
