Light pink/brown discharge..

Hi, I'm Cam and have VERY irregular periods. I do still ovulate, proven with ovulation strips. I haven't had a real period since my MC in November. Last week I started having very light pink on the toilet paper when wiping. It was off and on for a few days. Yesterday, Sunday, I had brownish discharge and it was VERY light... I could only see it on the toilet paper but felt very wet... just wondering if anyone else with irregular periods or not have had this and what was the outcome.. period? Positive pregnancy test? We're trying for our first but will be my rainbow baby. 💜
