Have to start TTC for 2nd baby, having some complications

Naina

I have to start my TTC journey for second baby but before getting into this I need to clear one major doubt I am having, I have breastfeed my baby till 2 years and because I need to start for 2nd baby, forcefully I have stopped BFing 😢, it was very hard but I have to. Now ever since I have stopped her BFing my period cycle have become very irregular with that dates and flows, last month first time I tracked my LH surge through OPKs and got my clear positive on CD20 and did calculate when I should be getting my period and did got on time too but flow my period is very low I usually have very heavy flow, does it sound normal ?? It's ok start my TTC journey or should get this fully tested by doctor ? Thanks in advance.
