Don’t Judge But…

So I don’t know if I could be pregnant. Should I take a pregnancy test at this stage. For context, I’m 8 months pp and I exclusively pump, my period has been back since 12 weeks pp. But my husband and I have been sexually active since 6 weeks pp. He’s team pull out. But recently he’s not pulled out twice. So the first day was 04/09 and I took emergency contraception on 04/10, my period starts 04/15 (it was supposed to start the 14th) So everything was normal right?? Well he did it again on 04/23, and I took emergency contraception on the 24th. But since the first one I’ve been excessively sleepy, nauseous, having hot flashes, feeling light headed, and even collapsed in the shower, also I SWEAR my stomach has been feeling weird. I might be crazy, but maybe… for reference neither me nor my husband is against another kid, I told him I refuse to take another plan B because I don’t like them. The only reason why he doesn’t want me to have a baby is because he’s scared. My last pregnancy was immediately after the first, and the doctor advised us to wait at least 18 months before having another because my uterus needed time to recover. Idk though I personally feel like she was just trying to scare us. People do it everyday and are fine. I’m young, healthy, low risk, went full term both times, and went into labor naturally both times. Should I wait??? I’ve been having serious urges to have another 😩
