Cramping / Painful intercourse

Okay ladies. Need some sort of reassurance. I had my baby one year ago. I did not have sex for over a year. When I finally did the first time was normal. The second time afterwards my pelvis hurt for a week. We used a condom and I’m not sure if that caused the pain as things could have been lubricated more. Fast forward to this month and my period is here and I am cramping. I never cramp with my periods but this time is different. It’s a dull ache in my suprapubic area. I have not been hydrated like I should be now that I don’t nurse anymore. Should I be worried? My appt with my gyn is a month away.
