doggy style and pregnancy...???

so I'm 7 weeks and my husband and I were just getting started and it hurt a litt lil d but but I ignored it because well I dont mind a little bit of pain but then he trusted and omg I just started crying. it hurt so bad. I ran to the bathroom checking for blood like I'm terrified it could make me miscarry. is this safe? first time ever being pregnant... p.s. there was no blood, no spotting.
