Working out while pregnant ???

Silvia • Irregular periods. 13 years together with my husband. Trying to get pregnant with our first baby. Fingers crossed!!!
I'm not afraid of labor but I'm defiantly afraid of  gaining too much weight during pregnancy . I'm pretty active now and workout 6 days out the week. At this point I would honestly give up anything to get pregant, but I'm curious to find out how much is too much working out during pregnancy or the what type of workouts to avoid. Thoughts???
