Implantation ?

Sarah • TTC baby NO.2

I never experience implantation before so I’m kind of confused if this is that or if it’s start of my period? I have very irregular periods and when I get them it’s never “light” even when it starts up so idk. But I took a pregnancy text and it was vvvvvfl. I plan on taking another in a day or two. Fingers crossed! Because my husband and I have been ttc baby #2 for 4 years ! ❤️🙏👶🏽
