I usually have really light spotting, pinkish, after my husband and I have sex. But the last time we had sex was several hours ago and I made a trip to the bathroom right after dinner and when I wiped there wasn't a lot of blood, just more blood than usual. Should I be worried? This hasn't happened before. I've been having light cramps that started when I started making dinner, but it didn't hurt, just felt like a tummy ache, like I had gas. I've had cramps like that before so I didn't worry too much about it.
