weight & ttc

Na
I currently weigh more than I did when I was full term pregnant with my one and only son. Mind you this was 10 years ago but can losing weight help conceiving? I haven't tried for another baby until my current marriage. Cycles have been irregular for the last couple of years. Docs say "all is normal & ive had a baby before so it lll happen again". 😑
Been taking vitex & maca & an organic multi vitamin since 01Jan17. Only difference I've notice is tender breasts like tonight, mild cramps and random vibrations in my pelvic area. Any advice??
