So ive noticed I have this line under my bellybutton. its kind of light but I can see it. I had sex on my period last July (19-23) I had sex on the 22nd pull out. My cycle is 27-30 days

I have had my period this august (4 days early) (August 15-19) then I had protected sex on the 22nd of August. Condom and made sure there was no leak :)

pictures below are my period lmao just to make sure bc some states that they had periods when they were pregnant. Im safe right?
