Implantation bleeding ?

Hollan

Has any experienced implantation bleeding?. Yesterday I had some random bleeding and it only lasted for about an hour. It was red and pretty light. Not heavy at all. I still have 10 days until my next period. So. I’m not sure what’s going on. I didn’t have implantation bleeding with either of my kids. my youngest is 8 months. And her and my oldest are 2 years apart.

We are not actively trying to get pregnant . But for a while I wasn’t on birth control because I wasn’t getting periods. And I just got my first period so I just started back on birth control. So could it be possible that I’m pregnant or is it just break through bleeding. (For me break through bleeding never lasted less than 2 days and started immediately with the first pill. But I’ve been on it for going on 9 days now.) so I’m just confusedddd. We were having sex ALOT. Around the time I got my first period and even after it.. and I’m thinking I could be in that window. Helppp. If you’ve had implantation bleeding what was it like for you? If you’ve experienced random 1 hour bleeding before, We’re you pregnant ? If not did you ever figure out what caused it?
