Cramps the morning after sex

Ju

Sorry for tmi but I’ve stayed away from sex for the last 2 weeks as I felt pretty ill. We had sex last night and this morning I’ve woken up to cramping. It’s scaring me as last pregnancy we had sex then miscarried 2 days later... I’m terrified the same thing is going to happen. Any advice or thoughts would be appreciated. I’m 6 weeks pregnant. X
