Pregnant, single and horny

In the process of divorcing an alcoholic, abusive husband in jail so consider myself single and although there is a guy friend who is interested despite me being 23wks prego...I can't fathom another man's dick in me with my exes kid inside. With my first....I remember amazing sex with my husband while prego. Fingering myself is making me want toys(never owned any)....are toys ok while pregnant? petrified of waddling into a sex store alone to buy one. Tips, advice???
