Vagina/pubic bone pain?

Anyone else experiencing this? I’m only 13 weeks, but I’ve been feeling this pain off and on for atleast 4 weeks now. It’s not like a pain in my vagina, more like at the base where my bone is in my crotch. The best way to describe it is it feels like someone kicked me in the crotch and it aches! The pain isn’t constant though, it comes and goes randomly. I’ve also felt weird spasms (almost like contractions) in what feels like my cervix. It’s so hard to describe! Again, this is random and sporadic, and it almost just feels like clenching and unclenching up in my vagina where I assume my cervix is. I don’t think sex is the issue (it’s been about a week since the last time) and I’m not doing any sort of rigorous activities or heavy lifting. I have a desk job and come home and lay on the couch all night. Anyone else going through this and know the cause?
