Cryptic pregnancy?

Back story.

Husband and I have been TTC since February 2017. I've had some fertility issues my husband is fine although I have anovulation problem. I took Clomid in the month of June and September.

The first day of my period in July was the 10th I had a regular period that month. In August I was 18 days late so I was on a cycle of 50 days I went to my OBGYN and she told me not to worry about it that it was normal for women to miss a month or two and be fine. She ordered a blood drawn to check my thyroid. It was normal. I then I had a normal period in September and here we are in October and I am 7 days late I took a test this morning and it was flat out negative. I've noticed highten sense of smell and sleepiness. I've had a period since I was 12 years old every month like clockwork and now it wants to be all crazy. I know Clomid can kind of mess up your Cycles but I didn't even ovulate on either cycles of taking it. And I had a perfect cycle each time after taking Clomid. Last night as I was laying in bed I had a sneeze attack because my cat's fur messes with my allergies and I felt this very strange sharp tugging feeling in my lower stomach and It didn't last very long. Maybe 3 seconds but I could definitely feel it. Later than that night I felt a roll in my stomach. It wasn't gas pain a bubble or anything I've ever felt before. It literally felt like a small ball in my stomach jumped. So I'm not sure what's going on with my body. I go to see my OBGYN tomorrow so hopefully I get some answers. 😒
