Hi all :)
There's a chance I could be pregnant (no condom used) and lately I have been having these weird flutters. Today I started to feel a quiver at the bottom of my abdomen so could that mean anything or no?

You would have to be fairly far into a pregnancy before you notice the flutters. Most women will already know that they are pregnant before they start to feel it.
Since there is the chance of pregnancy, maybe try a pregnancy test. Have you missed any periods... or had ones that were a bit off from your norm? Could be just air bubbles... I have felt very similar feelings to baby's first movements and there is no possible way I was pregnant.

My last period left 2 days early. Ill try a test though just to be sure

The earliest people usually feel flutters in their first pregnancy is around 16-18 weeks so I doubt that these flutters mean you are pregnant BUT having unprotected sex could mean you are pregnant regardless so you should take the test and take this as a lesson learnt about unprotected sex. Also don't forget that sexually transmitted infections are so easy to pick up, so getting tested for those would be wise too!
