Does lower stomach feel hard then end up 🤰🏽?

Two days till my period me and bf had sex every other day during fertile window had sex on my peak but not on ovulation day .. but I never cramp when my period comes tho but since the other day just a lil and lower part of my stomach a lil hard lol but I remember when i was like this before even tho I was two weeks late thought it was from stress tho went to the dr I ended up finding out I was pregnant with my 1yr old but anywho I’m scared to take a test bc it hurts me when I see a negative then my period comes 😫.!!
