Hi all!

TDLR; my period is 23 days late but pregnancy test shows no hcg hormone.

So, I’ve noticed that my cycles have been getting longer. 3 months ago it was 33 days, then 35 the next and last month it was about 40. Today is day 51.

I wasn’t sure what was going on, but then I realized it may be my new roommate who is female. Could it be possible that we could be syncing? If we were would be period really be a whole month late?

Nothing really in my lifestyle has changed. My diet is relatively healthy and I don’t have any major health problems.

I took a pregnancy test two days ago and it was negative.

I’m not sure what to do. Please help.

Thank you in advance!!
