Hi @VB, welcome to the Community I'm afraid that goals, cards or any other odd that you've placet a bet on "Regular time" and it happens on OT do not count unless the bet you place specifically states that it includes overtime. The terms below should cover it, sorry for the inconvenience.
"1) Unless listed either in conjunction with the bet offer, or else in the Sport Specific rules, all bets should be considered valid for the result at the end of the "Regular Time" or "Full Time" only. "Regular Time" or "Full time" is defined as interpreted by the official rules published by the respective governing association. For example, in football, full time is stipulated to be 90 minutes including injury time, and in ice hockey it is stipulated as the 3 x 20 minute periods. Should the governing association decide to stipulate, before the start of the event, that the said event is to be played over a different duration, this will be treated as being the official rules for the event (for example, Under 17 football played with 2 x 40 minutes). Nonetheless, such occurrence is limited to the "regular" playing time and does not include any prolongation such as extra time or overtime, unless explicitly stated."
