Period Late

Ashley

Okay guys, so my husband and I have just recently started TTC. I came off BC at the beginning of may and have had 2 normal cycles since then. However I am currently 9 days late for my period. I have taken 6-7 pregnancy tests and all are very clearly negative. I have never had irregular periods before so I’m not sure if this is normal?! What else could cause my period to just complete skip? Does this mean I didn’t ovulate this month as well?
