Worried

So my fiancé broke up with me, he said he needs to work on himself and he doesn’t want to put me through a relationship with him while he’s dealing with anger issues and everything else. So fine I respect his decisions and left to give him the time and space he needs. But we had been trying to get pregnant for months prior to this and every month our timing was off except this last month we timed everything perfect, used ovulation tests, the whole 9 yards now I’m a week late and terrified to even take a test and I’m just waiting to see if it comes and maybe it’s just delayed from the stress of everything. I’ve been so nauseous and sick feeling and with everything going on I can’t even pinpoint why. I just need to tell someone because this is such a worry I’ve been having that is a complete secret from everyone.
