Hello I appreciate your query. It is commont o have some amount of spotting / bleeding after embryo / blastocyst transfer. You must be taking medications for the IVF luteal phase support, hence the other symptoms are non specific. You must monitor your blood pressure as that could cause dizziness, as well as the medications for dizziness. As for the chances of your pregnancy, your infertility consultant could tell you how well your IVF cycle went. Also, the type of bleeding that you described does not rule out your chances of conception after blastocyst transfer. You would know for sure only after your B-HCG levels are tested as recommended by your consultant, to know whether the IVF cycle was successful or not. Please do not worry or panic till you know the result for sure, as minor bleeding does not rule out chances of pregnancy. All the best !
