advice please

Ladies a bit of a long one..... so been ttc with df since august last year... my af is always on the 1st of every month... this time af decided to come a week early (never does) and start off spotting for 2 days ( only there when wipe), heavy flow for one day and bad cramps, followed by medium flow and then back spotting... for the last day or so iv had crampy feeling in my lower stomach/ pelvic area.. haven't ovulated yet and obv not due af for another 3 weeks (fingers crossed won't show for another 9 months 🤞🏻) iv recently started taking folic acid and going to try the pineapple core... my question is. Have any of you tried these and have any of you had the crampy feelings (like as if due on...)??
