Yes, my dear, they are incredibly similar because of the progesterone hormone rise in both cases. Breast soreness, mild cramping, and bloating can happen in both. Try to stay calm and just wait for your period date to do a test, don't stress your mind.
Yes, the body behaves very similarly in both situations, so it is hard to distinguish. Keep your faith strong, stay positive, and don't overanalyze every little ache. When the time is right, everything will become clear to you. Take care of your health.
Because of my PCOS, my cycles were always erratic and PMS symptoms were very confusing. Early pregnancy symptoms like breast tenderness and mood swings felt exactly like PMS to me. It is highly tricky to tell them apart, so a home test kit is the only reliable way to know.
They are so similar that I actually thought my periods were coming and even asked my mother to make me some hot ginger tea for cramps! But then the dates passed and we realized it was pregnancy. It is very natural to confuse the two.
In my experience, they felt almost identical in the beginning! I had the exact same lower back ache and cramping that I usually get before my periods. The only real difference I noticed later was that the mild cramping kept going but the period didn't start.
