Is this due to ovulation or what (details below)?

I have my end term July 28 (14 days ago). I hade sex around 7 days ago, which be too hasty within the cycle to gain pregnant.
Yesterday and today I have a feeling a stomach-ache, close to I do sometimes when I am ovulating. However, usually it simply last afew hours, immediately it have last 2 days and I also hold some blood (spotting). It's never happen to me past. Could this be because of ovulation, could I be pregnant and own implantation bleeding? Any experiences?

It could be from ovulation, some spotting is ordinary during ovulation. There is a righteous randomness you could be pregnant though if you have unprotected sex. It be not too hasty contained by your cycle to grasp pregnant. Sperm can live surrounded by the fallopian tubes for 3 - 7 days. There's even be a suitcase documented where on earth a women get pregnant 8 days after that.

Edit: As long as you didn't ovulate rash next yes it would be rash for implantation bleeding. Implantation bleeding usually occur 6 - 12 days after ovulation.
Do you hold clear stretchy discharge, that's one of the best signs of ovulation.
