As it is so early, it is very common for pregnancies to end themselves, for any reason or none. Just that the body rejects continuing with that pregnancy. Therefore, it is possible for a woman to 'encourage' what might have happened anyway, by nature. Your body and brain rejected pregnancy the first time. You barely got through it. Your body and brain are again saying "no".
Who would benefit from trying to force yourself again, and quite possibly never getting out of it again, this time? Not you, not your lovely child, not your effectively single-parent plus wife's-carer husband, and above all not the bunch of cells inside you, destined to arrive in the world with, in effect, no mum, and an overwhelmed dad, a once-happy big sister deprived of her once-happy, stable, parents and her security?
There's no need to announce to husband or to anyone that the ending was brought about deliberately. One method of 'encouragement' is to have a coil fitted, which has the advantage of stopping yet another pregnancy. Regrets about stopping being pregnant are trivial, compared against regrets of an entire family that their once happy life is spoiled, and regrets and lifetime unhappiness of a child who was a mistake, especially one who discovers s/he destroyed his/her mother's mental or physical health.
In time, if you enjoy looking after children, you could do that for a job, or try fostering or adoption. That way, your hormones won't get upset.
