Question PLEASE READ 😢😔🙏🏽

Sooo is it normal to have brown spotting and light cramps before periods??? So here’s the thing: I have ALWAYS had irregular periods due to a hormonal imbalance. I would get a period every 4-6 months. I had unprotected sex with my husband like 5 weeks ago but he withdrew and never ejaculated inside of me (I know it’s not safe but oh f*cking well.) so a couple weeks later after he gets deployed I start spotting a little bit but NO cramps. I take a pregnancy test and I got a negative. Then I have a sharp pain in my ovary and get a small amount of clear stretchy discharge ( ovulation discharge but not as much as I usually would get so I’m like okay I’m ovulating) but this ovulation seemed more painful because I had back pains as well so my paranoid ass thinks I’m pregnant and I take a pregnancy test once everyday for 5 weeks straight to this day and they’re all negative but NOW I’m breaking out ( breasts arnt sore because they’re not sore EVERYTIME I ovulate anyways) and I’ve been spotting very light brown discharge AGAIN for a few days and had light cramping. ALL pregnancy tests NEGATIVE. haven’t had sex in over 5 weeks. I swear I ovulated like 2 weeks ago. And I have been EXTREMELY STRESSED OUT because I want my period to be over with. Any advice would be MUCH appreciated. I don’t think I’m pregnant but I do still get paranoid because google f*cks with my mind .when I research spotting all I get is pregnancy bullsh*t.(sorry for the language I’m really frustrated with this whole damn situation if you can’t tell.) any advice would be MUCH appreciated 😔🙏🏽😧
