I doubt if there's any sense in it. They probably decided you are female and of fertile age.
They worked out my age - not hard to do from my posts. So I get ads for life, health and funeral insurance, and everything oldies are imagined to "need." They even bombard me with diet ads, exercise regimes and elastic compression underwear -- the last things I need since I'm in good shape and have a healthy natural diet and good varied exercise.
Ad people are nuts. They don't care how many people they annoy as long as a few fall for their cons.
I think most of the time their algorithms are based on market research demographics and probabilities rather than anything personal. If you were signed up to frequent-flyer points or if you bought stuff via the internet they could target your preferences and needs more accurately
I suppose I should be at least a tiny bit grateful that such ads make Internet services nominally free, but I would appreciate if occasionally an ad showed me something I might actually want...
I can't imagine how looking at car detailing products, recliner chairs, Lenovo laptop chargers, and LED flashlights made the algorithm go "That cockatoo needs period-proof underwear!"
