Dull ache at 7dpo

Hey ladies! Me and hubby DTD on the 24th, which according to Glow, is the day i ovulated on. We did it again on the 25th and 26th. Around 4 dpo (TMI ALERT), i had a TON of watery cm up until 5 dpo. I am currently 7 dpo and I've been having a dull ache on my pelvic area. Its sort of like period cramps but it doesn't hurt its just very uncomfortable. I can't really describe it, its hard to put it in words. My question is: should I be concerned about this? Or could it possibly be related to early pregnancy? Any and all info would be appreciated! Thanks again girls☺️
