Cycle Syncing

I know a lot of people say it ain’t a thing, but, my cycle synced to a co-worker and our cycles come at the same time.

She just announced she’s pregnant, and I’m over 3 weeks late now myself.

Has anyone heard of your cycle buddy causing your own cycle to stop when they get pregnant?

I know it’s a weird question, but I’m late, no period, no positive tests, but I’m having the emotional swings, the sore nipples and back pain... but no positives tests.

I’m so close to just getting beta HCG test...
