I don’t get it...PIC


I started testing as soon as I saw my fertility window in my calendar (I’m regular). On Monday Feb 5th I started feeling cramps while I was out and when I went to the restroom as I saw vaginal discharge. I figured I was about to ovulate...so when I got home I tested and it was positive. After that I continued to test until I saw a faint line. Well, the cramps haven’t gone away since last Monday and last night I saw vaginal discharge again (after intercourse) I figured it was just because I had just finished having sex but then today I tested just in case and ITS POSITIVE. Again? I don’t get it. Is that even possible? Now I’m confused because I was expecting my period this weekend and I was so excited to test for a BFP and now i feel like my Days will be all off
