Feeling like I'm on my period when pregnant? 😂

Does anyone else ever feel like they're about to start their period even though they're pregnant?

I'm 16 weeks now and I swear every month around the time that my period would normally start I get all my period symptoms like I'm about to start. Sometimes it worries me cause the symptoms are really strong (really really sharp cramps. Worse than the ones that ive had throughout the pregnancy so far.)

It's just the weirdest feeling. Before I could tell exactly when my period was starting. (Id stand there & just be like "shit my period just started" & id rush to the bathroom just in time to get myself situated before my panties got any blood on them- sorry if tmi) and I still get that feeling now. It's crazy! Has anyone else experienced this? Lol
