Massively confused!

I started tracking my cycle in December and we start ttc in jan. I thought initially I was as having symptoms but negative tests made me think I was just over thinking it. I then got my period and thought no more of it. I then forgot to track this month, took a ovulation test today which showed I was at peak ovulation. Now I don’t know what made me do it but tonight I’ve taken a pregnancy test which came back as pregnant. I’m thinking it may be a false positive and will repeat in the morning but has anyone else had this? My brain is baffled
