Detailed Answer:
Hello,
Thanks for the query to HCM,
HERE IS AN EXTRACT FROM THE LIST OF SAFETY PRECAUTIONS FOR HYACINTH BEAN:-
Side Effects And Warnings

Hyacinth bean may cause flatulence (gas).
Hyacinth bean may decrease the risk of bleeding. Caution is advised in patients with bleeding disorders or those taking drugs, herbs, or supplements that may increase the risk of bleeding. Dosing adjustments may be necessary.

Use cautiously in patients using fertility agents or in women trying to become pregnant, as hyacinth bean may have birth control effects.
Avoid consumption of dry seeds from the hyacinth bean plant, as they may be poisonous; seeds from the hyacinth bean plant should only be eaten after prolonged boiling.
Avoid in pregnant or breastfeeding women, due to a lack of available scientific evidence.
Avoid in individuals with known allergy or hypersensitivity to hyacinth bean (Lablab spp.), its constituents, or members of the Fabaceae family, such as peas and beans.

Pregnancy And Breastfeeding

Avoid in pregnant or breastfeeding women, due to a lack of safety information.
Information on hyacinth bean's effects on lactation is currently lacking in the National Institute of Health's Lactation and Toxicology Database (LactMed).

Anyhow you are in your 28th weeks, so as most of the musculoskeletal system and neuromuscular system is already formed by 14th week of gestation, so foetus is not at any risk of any congenital anomaly or jeopardy, as just a bowl of hyacinth bean should not cause any harm at all, unless you have developed any allergic symptoms after intake. So you are asymptomatic, baby is safe. Relax.
