Wacky periods!

My husband and I have been ttc for 5 months now. I know that’s not that long in the ttc world. Immediately after our first month of trying to conceive my period comes a week earlier than before ttc. What is going on ? It seems to start very slow and lightly. I always think it’s possibly implantation bleeding. The timing always seems right. Then it turns out to be a full period. My period before ever trying to conceive was not regular but it came later in my cycle. It always came on heavy and last 7 days or so.

Has anyone else experienced this? Thank you for any insight. It’s driving my crazy lately.
