Oh shit please help? Am I pregnant again?

Melissa • Mummy to two coming 3 (due August) beautiful children.

I am only 7 weeks pp. me and my boyfriend in the last 3 weeks have had unprotected sex 3 times. Once a week. 3 weeks ago, we had sex, and he pulled out. But then 3 days later, admitted he didn't think he pulled out completely. But that he might have so he rhinks we are ok. So I didn't get any morning after pill. Then last week, we had unprotected sex again. And this time he deff didnt pull out, so I got the morning after pill right away. Then we had sex again there on Thursday morning. Again, I honestly have no idea if he managed to pull out on time but said he did. And now today I've just went to the loo to find what looks like spotting. 4 weeks pp I was due a period, but didnt get it because I'd bled for so long after I had the baby. She's now only 7 weeks, so I'm not sure if it's a period coming on. Or spotting. HELP!!! If I took a morning after pill a week ago, it couldn't be pregnancy could it? Please don't start being negitive abourmy stupidity. I'm well aware of it 😭😭😭..... its the lightest pink colour ever
