Sarah • ttc jan 2016 - loss 10/25/16 & 02/22/2017
So I had a miscarriage exactly a week ago. Yesterday my bleeding / cleansing had basically stopped. This morning for the he'll of it I took an ovulation strip. It was positive?!?! From everything I've read it's normally to ovulate 2 weeks after a miscarriage. But 1 week after a miscarriage??? Has this happened to anyone else?? Help!? I would love to be so we can get back on trying again asap!
