My husband works a completely opposite work shift from me. We went from being able to have sex at least once a week to maybe once a month to no sex and now because there are some unusual spots in my uterus on ultrasound next to baby. So now it's no sex at all until I am cleared. He says it's either marks from placenta moving or it could very well be blood clots. Doctor said husband can use his hands or mouth but that's it lol. Anyways anyone else go through this? Did it end up being blood clots? If so what happened? Did you need to stop working or put on bed rest? 21 weeks pregnant btw.
