Reasons for spotting?

I had sex (not for the first time) on saturday and be lightly bleeding without hesitation after, and I've had spotting ever since. My extent is due tomorrow, and I have be stressed this month, so it could be ovulation spotting and I'm just ovulating unpaid, only I've never have ovulation spotting before, and I have a feeling it has more to do next to the sex, since it happened right away after. I've heard of implantation spotting, too, but I hadn't had sex in almost 2 weeks prior. Is there anything else it could be? If it be just rougher than usual it could split, too, but would I still be spotting 4 nights following?

It could be that it was only sex that did it. It could be that you are starting your period immediately and are just really street light. It wouldn't be implantation bleeding, so don't worry roughly speaking that. Sometimes, girls who have sex for the first time can bleed for a few days after. If you are getting close to time to start, it could simply be that sex disrupted your cervix enough that you are bleeding a touch. Just watch it and if you are hurting, or surface like it isn't convalescing, talk to your doctor. More afterwards likely, it isn't anything to verbs about.

Are my measurements OKAY?

Maybe your hymen is in a minute completely broken, and wasn't before? Did you wear protection or are you on birth control? Wait and see if you procure your period and if you're still regular. If you are, next maybe it be just cause by rough sex. If not, see a doctor or buy a pregnancy test.

Best of luck
