Hey mamas! Sorry in advance for the long post. I was just wondering if any of you have experienced or know someone who has experienced what I’m going through

So! My husband and I are trying for our last baby. I had my last period July 19th. We did the deed a couple of times during my fertile window and ovulation. Fast forward to now, I have missed my period completely, I’m having ALL of the pregnancy symptoms, my cervix is still high and closed, absolutely no spotting or bleeding whatsoever, BUT all my tests are coming back negative. This has never happened to me before, I’ve been very regular up until now, so it’s safe to say I’m very confused. I did set an appointment with my doctor next week to make sure everything is ok. But I’m interested to hear any similar stories! Do you think there could be a chance that I’m ACTUALLY pregnant??
