Had a very light period. Now I’m spotting?

I just got married on Oct. 5th yay! My husband and I went on our honeymoon and and consummated the marriage more than once lol. We haven’t used condoms in about a month or 2. We’ve been using the pull out method. I mean whatever happens happens. 🤷🏻‍♀️ is kinda the mind set we’re in. We’re not actively trying but. You know.

Anyways. I started while we were on hour honeymoon Disney Cruise. On the 8th. I was supposed to start on the 10th. Which is fine. I’m never exactly on time. I’m close to it though. So I started. But I honeslty didn’t even need a tampon or pad. The next day I spotted. Again assumed my period. But I maybe needed a tampon or pad a total of 5-7 times. That’s while trip. Didn’t even sleep in one. I finally noticed the spotting or light period go away around the 12th.

2 days later I went to the bathroom and spotted pink. Then it was gone. Found it odd but didn’t think much of it. Then today I spited brown this morning. Again. It’s gone now. Not sure why I’m spotting again?? It’s weird. I am cramping though, feel bloated and have some lower back pain. My boobs feel a bit sore but I think I’m just paranoid now. 🤷🏻‍♀️

Help?
